Why is detergent insoluble in hard water?
The functional group in a detergent is SO3 Na and this does not react with the calcium and magnesium ions in hard water. When soap is dissolved in hard water then it forms a scum but in case of detergent scum is not formed hence detergent is insoluble in hard water.
Why don’t detergents and soaps work in soft water?
Naturally occurring soft water does not have these minerals present and therefore detergents and soaps do not react as they do in hard water.
What is the difference between soap and detergent and hot water?
Warm or hot water melts fats and oils so that it is easier for the soap or detergent to dissolve the soil and pull it away into the rinse water. Detergents are similar to soap, but they are less likely to form films (soap scum) and are not as affected by the presence of minerals in the water ( hard water ).
What is hard water in laundry detergent?
Hard water is water that has an excess of minerals in it. The minerals inhibit the foaming agents, reducing the effectiveness of the detergent. That’s because the soap in the detergent chemically interacts with the minerals in the hard water, neutralizing them so they can no longer dissolve in water.

How does hard water affect soap?
Water Hardness Affects Soap’s Cleaning Action 1 Hard water reduces the cleaning capacity of soap. Soap lathers readily with soft water. Rainwater is naturally soft. In contrast, hard water does not produce a good lather, so it is more difficult to wash with soap in hard water. It is also not recommended for bathing, laundry, and laboratory purposes. The minerals in hard water react with soap and affect its cleaning capacity. It’s still possible to use hard water when washing by using more soap. The additional soap will no longer be affected by the minerals in the water, so they can clean just as effectively, but you’ll be wasting more soap this way. Water gets hard as it passes through rocks and soil absorbing minerals from the environment or from man-made pollutants. 2 Hard water and soap produce a curdy precipitate called soap scum. Hard water has a high concentration of dissolved minerals like calcium ions and magnesium ions in the form of dissolved salts. Soap contains sodium salt from stearic acid. In soft water, this sodium dissolves easily, but in hard water, it binds to the minerals and produces insoluble calcium or magnesium stearate, also known as soap scum. Soapless detergents are made from propene and do not produce soap scum.
Why is water hard?
Water gets hard as it passes through rocks and soil absorbing minerals from the environment or from man-made pollutants. Hard water and soap produce a curdy precipitate called soap scum. Hard water has a high concentration of dissolved minerals like calcium ions and magnesium ions in the form of dissolved salts.
How does water hardness affect soap?
Water Hardness Affects Soap’s Cleaning Action. Based on how effective it works with soap in cleaning, water is classified into two types: soft and hard. Hard water reduces the cleaning capacity of soap. Soap lathers readily with soft water. Rainwater is naturally soft.
What is soap made of?
Soap contains sodium salt from stearic acid. In soft water, this sodium dissolves easily, but in hard water, it binds to the minerals and produces insoluble calcium or magnesium stearate, also known as soap scum. Soapless detergents are made from propene and do not produce soap scum.
How does soap work?
Soap molecules break down oil into smaller drops so they can be suspended in water. Soap works by pulling dirt and grease from your body into the water. Drops of oil are removed when you rinse with water.
Is it safe to wash with soap in hard water?
Rainwater is naturally soft. In contrast, hard water does not produce a good lather, so it is more difficult to wash with soap in hard water. It is also not recommended for bathing, laundry, and laboratory purposes.
Does soap work with hard water?
Soap is the most commonly used agent for cleaning and is more effective in removing dirt, but it doesn’t work well with hard water . Before we discuss why hard water doesn’t get along with soap, we need to discuss first how soap is made and how it works as a cleaning agent. Soap is the byproduct of a chemical reaction between fats and alkali.
What happens when soap molecules come in contact with hard water?
When the “soap” molecules come in contact with the magnesium and calcium in hard water, a chemical reaction occurs and magnesium stearate or calcium stearate forms; this is the waxy substance we all know as soap scum. This reaction prevents the soap from producing the cleansing lather as it was intended.
What is hard water?
Hard water, by definition, is water which contains a high concentration of calcium and magnesium ions; it is these minerals which prevents soap and detergents from being as effective as they should be. When the “soap” molecules come in contact with the magnesium and calcium in hard water, a chemical reaction occurs and magnesium stearate ...
Does soap react with hard water?
It is a completely different story for soft water. Naturally occurring soft water does not have these minerals present and therefore detergents and soaps do not react as they do in hard water.
Which has more power, hard water or soft water?
It is common knowledge that soft water, either naturally occurring or from a water softener, has greater cleaning power than hard water.
Does soft water require less detergent than hard water?
Not only does soft water require much less detergent than hard water to be effective , there is another cost savings benefit associated with soft water as well. Due to the fact that detergents clean more efficiently in soft water, washing machines do not have to be set on hot in order to achieve good stain removal.
What is a detergent?
Detergents are primarily surfactants, which could be produced easily from petrochemicals. Surfactants lower the surface tension of water, essentially making it 'wetter' so that it is less likely to stick to itself and more likely to interact with oil and grease.
What are the two elements that are used in detergents?
Alkalis: Sodium and potassium hydroxide are used in detergents even as they are used in soapmaking. They provide positively charged ions to promote chemical reactions. Helmenstine, Anne Marie, Ph.D. "Understanding How Detergents and Surfactants Work and Clean.".
Why are detergents and surfactants used for cleaning?
Helmenstine holds a Ph.D. in biomedical sciences and is a science writer, educator, and consultant. She has taught science courses at the high school, college, and graduate levels. Detergents and soaps are used for cleaning because pure water can't remove oily, organic soiling.
What are the two substances that are used to make surfactants?
Oxidizers: Sulfur trioxide, ethylene oxide, and sulfuric acid are among the molecules used to produce the hydrophilic component of surfactants. Oxidizers provide an energy source for chemical reactions. These highly reactive compounds also act as bleaches.
Do detergents have hydrophobic chains?
Like soaps, detergents have hydrophobic or water-hating molecular chains and hydrophilic or water-loving components. The hydrophobic hydrocarbons are repelled by water but are attracted to oil and grease. The hydrophilic end of the same molecule means that one end of the molecule will be attracted to water, while the other side is binding to oil.
Does soap or detergent pull dirt away?
Neither detergents nor soaps accomplish anything except binding to the soil until some mechanical energy or agitation is added into the equation. Swishing the soapy water around allows the soap or detergent to pull the grime away from clothes or dishes and into the larger pool of rinse water. Rinsing washes the detergent and soil away.
Do detergents contain surfactants?
Modern detergents contain more than surfactants. Cleaning products may also contain enzymes to degrade protein-based stains, bleaches to de-color stains and add power to cleaning agents, and blue dyes to counter yellowing.
