What is the color of ammonia?

Liquid ammonia is used extensively as a nonaqueous solvent. The alkali metals as well as the heavier alkaline-earth metals and even some inner transition metals dissolve in liquid ammonia, producing blue solutions. Physical measurements, including electrical-conductivity studies, provide evidence that this blue colour and electrical current are due to the solvated electron. metal (dispersed) ⇌ metal (NH 3) x ⇌ M + (NH 3) x + e− (NH 3) y These solutions are excellent sources of electrons for reducing other chemical species. As the concentration of dissolved metal increases, the solution becomes a deeper blue in colour and finally changes to a copper-coloured solution with a metallic lustre. The electrical conductivity decreases, and there is evidence that the solvated electrons associate to form electron pairs. 2 e− (NH 3) y ⇌ e2 (NH 3) y Most ammonium salts also readily dissolve in liquid ammonia.

Where does ammonia come from?

Ammonia occurs naturally and is produced by human activity. It is an important source of nitrogenwhich is needed by plants and animals. Bacteria found in the intestines can produce ammonia. Ammonia is a colorless gas with a very distinct odor.

How is ammonia produced?

Ammonia occurs naturally and is produced by human activity . It is an important source of nitrogen which is needed by plants and animals. Bacteria found in the intestines can produce ammonia. Ammonia is a colorless gas with a very distinct odor. This odor is familiar to many people because ammonia is used in smelling salts, many household and industrial cleaners, and window-cleaning products. Ammonia gas can be dissolved in water. This kind of ammonia is called liquid ammonia or aqueous ammonia. Once exposed to open air, liquid ammonia quickly turns into a gas. Ammonia is applied directly into soil on farm fields, and is used to make fertilizers for farm crops, lawns, and plants. Many household and industrial cleaners contain ammonia.

How is ammonia lost from water?

Ammonia is lost from water by volatilization (1). The Henry's Law constant for ammonia has been measured as 1.61X10-5 atm-cu m/mole (2). This Henry's Law constant indicates that ammonia is expected to volatilize from water surfaces (3). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec) (3) is estimated as 1.4 days (SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec) (3) is estimated as 12 days (SRC). Ammonia's Henry's Law constant indicates that volatilization from moist soil surfaces may occur (SRC). Ammonia is a gas with a vapor pressure of 7500 mm Hg at 25 °C and atmospheric pressure (4), and therefore, is expected to volatilize from dry soil surfaces (SRC).

How is ammonia converted to nitrate?

AEROBIC: When ammonia appears in water under the normal conditions (aerobic), it is rapidly converted to nitrate by nitrification; the principal water contaminant normally being nitrate. The pH in water is increased by the presence of ammonia ion, in the form of hydroxide ions. ... Bacteria convert the ammonia to nitrate creating an oxygen demand (BOD) several days after the introduction of ammonia. The bacteria that oxidize ammonia to nitrate are largely of the genus Nitrosomonas; conversion of nitrite to nitrate is carried out primarily by the genus Nitrobacter. Temperature, oxygen supply, and pH of the water are factors in determining the rate of oxidation.

What causes ammonia to react with acids?

Ammonia solutions react exothermically with acids to produce water and ammonium salts, Heating or treating with strong bases also causes evolution of gaseous ammonia. Ammonia can burn or explode if exposed to an intense source of ignition but can generally be treated as nonflammable. Readily combines with silver oxide, silver chloride, silver nitrate, silver azide or mercury to form explosive compounds. Forms explosive ammonium chlorate on contact with chlorates [Kirk-Othmer, 3rd ed., Vol. 2, 1978, p. 470]. Reacts violently or produces explosive products with fluorine, chlorine, bromine and iodine and bromine pentafluoride and chlorine trifluoride. Mixing of bleaching powder ( hypochlorite solution) with ammonia solutions produces toxic/explosive ammonia trichloride vapors. May react violently with boron halides, ethylene oxide (polymerization), perchlorates and strong oxidizing agents ( chromyl chloride, chromium trioxide, chromic acid, nitric acid, hydrogen peroxide, chlorates, fluorine, nitrogen oxide, liquid oxygen ).

What is ammonia used for?

Fresh household ammonia ranges in concentration from 5 to 10% NH3, but a 54% solution is also available commercially.

How much ammonia is produced in the human body?

Human adults produce around 1000 mmol of ammonia daily. Some is reutilized in biosynthesis. The remainder is waste and neurotoxic. Eventually most is excreted in urine as urea, together with ammonia used as a buffer. In extrahepatic tissues, ammonia is incorporated into nontoxic glutamine and released into blood. Large amounts are metabolized by the kidneys and small intestine. In the intestine, this yields ammonia, which is sequestered in portal blood and transported to the liver for ureagenesis, and citrulline, which is converted to arginine by the kidneys. The amazing developments in NMR imaging and spectroscopy and molecular biology have confirmed concepts derived from early studies in animals and cell cultures. The processes involved are exquisitely tuned. When they are faulty, ammonia accumulates. Severe acute hyperammonemia causes a rapidly progressive, often fatal, encephalopathy with brain edema. Chronic milder hyperammonemia causes a neuropsychiatric illness. Survivors of severe neonatal hyperammonemia have structural brain damage. Proposed explanations for brain edema are an increase in astrocyte osmolality, generally attributed to glutamine accumulation, and cytotoxic oxidative/nitrosative damage. However, ammonia neurotoxicity is multifactorial, with disturbances also in neurotransmitters, energy production, anaplerosis, cerebral blood flow, potassium, and sodium. Around 90% of hyperammonemic patients have liver disease. Inherited defects are rare. They are being recognized increasingly in adults. Deficiencies of urea cycle enzymes, citrin, and pyruvate carboxylase demonstrate the roles of isolated pathways in ammonia metabolism. Phenylbutyrate is used routinely to treat inherited urea cycle disorders, and its use for hepatic encephalopathy is under investigation. /Hyperammonemia/

Why is ammonia in water so high?

Slow-moving water: Slow-moving or stagnant water (see Figure 5) may have high ammonia concentrations because of lack of turbulence and volatilization and greater accumulation of metabolic waste and decomposition products —including ammonia (WHO 1986).

The more extensive the relevant sources and activities, the more likely it is that ammonia will reach concentrations that can impair surface waters.

What causes higher ammonia concentrations in the hypolimnion?

Lack of turbulence and mixing will decrease volatilization of ammonia, resulting in higher ammonia concentrations downstream. Thermal stratification in impoundments can lead to higher concentrations of ammonia in the hypolimnion which, with bottom-release dams, can result in increased ammonia in downstream waters.

What causes ammonia in sediment?

Ammonia in sediments typically results from bacterial decomposition of organic matter that accumulates in sediment. Sediment microbiota mineralize organic nitrogen or (less commonly) produce ammonia by dissimilatory nitrate reduction. Ammonia is especially prevalent in anoxic sediments because nitrification (the oxidation of ammonia to nitrite [NO 2-] and nitrate [NO 3- ]) is inhibited. Ammonia generated in sediment may be toxic to benthic or surface water biota (Lapota et al. 2000).

Septic seepage and failed package plants: Seepage from failed septic tanks or their leach fields, and discharges from poorly–functioning package sewage treatment plants may contribute significant amounts of ammonia to streams and lakes.

How does channel alteration affect ammonia?

Channel alteration can result in decreased nitrogen uptake within the stream, while decreases in riparian and watershed vegetation associated with agriculture and urbanization can reduce nitrogen uptake in the surrounding landscape. Channel alteration and water withdrawals can reduce ammonia volatilization due to changes in water velocities and depths.

Where is ammonia found?
