Is bromine an oxidizing agent?
Similarly, bromine is a more powerful oxidizing agent than iodine. Bromine can remove electrons from iodide ions, producing iodine; iodine cannot reclaim those electrons from the resulting bromide ions.
What agent is bromine water?
oxidising agentStatement-2:Bromine water acts as oxidising agent.
Is bromine a reducing agent?
Bromine lies below Chlorine, hence Bromine has a larger atomic radius than Chlorine. Since, Bromine has a larger atomic radius, the nuclear force of attraction on the electrons is less and hence Bromine can easily give away its valence electrons. Thus Bromine is a stronger reducing agent than Chlorine.

What does bromine water do?
Bromine water is used to identify the functional group present in the organic compound by halogenation mechanism.
Is water a reducing or oxidizing agent?
In the presence of a strong electron acceptor (strong oxidizing agent), water serves as a reducing agent. Water is rather weak as an oxidizing or as a reducing agent, however; so there are not many substances which reduce or oxidize it. Thus it makes a good solvent for redox reactions.
Is Br2 an oxidizing or reducing agent?
The half-equation is: 2Br–(aq) → Br2(l) + 2e– The chlorine gains these electrons, so it is the oxidising agent (becoming reduced to Cl– ions). The bromine has given electrons to the chlorine, so the bromide ions are the reducing agent (becoming oxidised to Br atoms, which form Br2).

What is an Oxidizing Agent?
An oxidizing agent (often referred to as an oxidizer or an oxidant) is a chemical species that tends to oxidize other substances, i.e. cause an increase in the oxidation state of the substance by making it lose electrons. Common examples of oxidizing agents include halogens (such as chlorine and fluorine), oxygen, and hydrogen peroxide (H 2 O 2 ).

Ionic examples include the permanganate ion, the chromate ion, and the dichromate ion.
What Factors Affect the Oxidizing Power of an Oxidizing Agent?
Oxidizing agents normally exist in their highest possible oxidation states and, therefore, have a strong tendency to gain electrons and undergo reduction. Ions, Atoms, and molecules having a strong affinity towards electrons are considered to be good oxidizers. The stronger the electron affinity, the greater the oxidizing power.

In fact, the oxidizing power of diatomic fluorine (F 2) is strong enough to cause metals such as asbestos and quartz (and even molecules, such as water) to burst into flames when exposed to it. A few other examples of elemental oxidizing agents include diatomic oxygen (O 2 ), diatomic chlorine (Cl 2 ), and ozone (O 3 ).
Which element has the strongest oxidizing force?
Elemental fluorine is said to be the strongest elemental oxidizing agent. This is perhaps due to the fact that fluorine is the most electronegative element in the modern periodic table, and therefore exerts the strongest attractive force on electrons amongst all the elements. In fact, the oxidizing power of diatomic fluorine (F 2) is strong enough to cause metals such as asbestos and quartz (and even molecules, such as water) to burst into flames when exposed to it.

What is chlorine and bromine used for?
Chlorine and bromine based biocides are widely used for microbiological control in cooling tower systems. These halogen compounds form strong oxidizing agents in water, which is how they kill bacteria and other microorganisms. Routine testing is important to confirm effective halogen residuals are maintained.
What happens to the halogens in biocides?
Most of the halogen added during an oxidizing biocide addition is consumed by demand reactions and off-gassing.
Why is it important to understand the oxidizer demand when treating a cooling tower system?
It’s important to understand the oxidizer demand when treating a cooling tower system. A high demand translates into higher oxidizer feed rates, and can make it difficult to achieve an effective free residual without a potentially corrosive high total residual also being developed. The relationship between the free and total residuals provides valuable information that can be used to help identify and troubleshoot systems with a high oxidizer demand.
Why add oxidizer to cooling tower?
To maintain a sustained residual, sufficient oxidizer must also be added to compensate for losses due to off gassing as the water circulates over the cooling tower fill, which can be significant. These losses are a function of the oxidizing biocide, pH, and cooling tower design/operation. Stabilized biocides release free chlorine and/or bromine on a controlled basis to reduce losses due to demand reactions and off-gassing. Their lower reactivity and volatility translates into a more persistent residual at lower feed rates.
What is combined halogen residual?
Combined halogen residual measures the concentration of oxidant that has been consumed in reactions with any ammonia, nitrite, or organic nitrogen to form a range of chloramine and/or bromamine compounds. Unlike chloramines, bromamines can be effective biocides.

Unlike chloramines, bromamines can be effective biocides. Where a stabilized chlorine or bromine biocide is used, it also measures the oxidant bound to a nitrogen based stabilizer. Total halogen residual is the sum of the free and combined chlorine and/or bromine residuals. Because bromamines can be good biocides, ...
Is bromine an oxidizer?
Unlike chlorine, bromine is an effective oxidizer across the pH range in which cooling towers operate. Some halogens generate both chlorine and bromine. The free residual does not vary with changes in pH.
