Hard water does not produce lather. So soap does not work effectively with hard water as soap does not form a good lather with hard water.
scum
no. soap cannot be used in hard water
Mineral ions from hard water (generally calcium and magnesium) react with soap forming insoluble and diasagreeable precipitates.
detergents are the sodium salts of alkyl suphonic acids. They contain a sulphonic acid group istead of a carboxyl group. soaps are made up of Na and Mg salts of organic fatty acids. detergents react even with water since they do not form scum, due to solubility of Naq and Mg salts in water. While soaps donot lather with hard water as they form scum.
Hard water contains the salts of calcium and magnesium, which neutralize the soap. So that more or less amount of soap is precipitated before you get the effect of soap on the water. Only after you have wasted the certain amount of soap, you get the foam in the water. The ability of soap to clean the clothes comes only after foam formation.
Detergents are also called soap less soaps becoz though they act likea soap in having the cleansing properties, they do not contain the usual soaps like sodium starate. detergents are better cleansing agents than soaps because they donot form insoulble calcium and magnesium salts with hard water, and hance can be used for washing even with hard water.

not sure. try someone else this is what i was looking for to : ( h2o Hard water
The effect of sodium carbonate on soap can differ depending on the type of water used. Hard water could cause the soap to bubble more, while fresh water could cause the soap to not bubble at all.

When soap is used with hard water, a scum is formed and it;Might damage the fabric.Makes the need of more soap for cleaning.One of the reactions involved in forming the scum is;2 C17H35CO2-Na+(aq) + Ca2+(aq) --> Ca(C17H35CO2)2(s) + 2 Na2+(aq)
Soap prepared by the reaction between fat (or oil) and sodium hydroxide is called hard soap. These soaps are used only for washing.
Soapy water is water which has soap dissolved in it.
It is used for removing permanent hardness of water.
1. it is used for softning of hard water. 2. it is used in manufacture of glassand soap. 3. it is used for washing purpose in laundry. $@ND#U
