How is soap scum formed?
The electronic charge that each of the two functional groups posses are opposite and thus attracted to each other. This causes a neutral charge to occure and the lipophilic portion of the soap molecule takes over. Soap scum is basically a smear of fat with metal ions crusting it.

Why hard water consumes a lot of soap?
The calcium (as calcium carbonate) in hard water replaces the sodium on the fatty acids of the soap causing them to precipitate as a sticky scum. This deposits soap scum on the things being washed and causes the formation of "bathtub ring" on bathtubs, sinks, etc.
What are the two form of hardness found in water?
Hardness in water is usually characterised as temporary or permanent. Both are due to the presence of calcium or magnesium ions. If they are present as the hydrogen carbonate, when the water is boiled this is converted to the carbonate which precipitates out as a solid, leaving water which is no longer hard, so this is called temporary hardness. If they are present as the sulfate the solution is unaffected by boiling, and this is called permanent hardness.
What is the difference between scum and scale?
Scum is created when calcium ions (and or magnesium ions) form an insoluble precipitate with soap. Soap consists of sodium salts of fatty acids. e.g. sodium stearate (aq) + calcium ions (aq) = calcium stearate (s) + sodium ions (aq) Scum is the calcium stearate. Limescale is created when hard water i heated, or when it evaporates. It is formed because calcium hydrogen carbonate is unstable. Ca(HCO3)2 (aq) + heat = Cac03 (s) +H20 (l) +CO2 (g) calcium hydrogen carbonate + heat = calcium carbonate + water + carbon dioxide

What S forms when soap is used in hard water?
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.
How can Hard water convert into soft water?
Hard water refers to water that has very high mineral content, which affects its behavior in pipes and its affect on other chemicals like soap, where it often causes the formation of soap scum. Hard water also has a tendency to form deposits in pipes. Normally you wouldn't WANT to make water become hard, and there are systems for trying to reduce the "hardness" of water in the pipes of your home.

What is the result of a hard water and soap solution?
Scum - calcium and other metal salts of fatty acids

What does the word scum mean?
Scum means - A filmy layer of extraneous or impure matter that forms on or rises to the surface of a liquid or body of water. Or The refuse or dross of molten metals. It is also used as a term of detriment to people ,to mean low life, "he is the Scum of the earth"
What does the word floccalation mean?
To form a scum on the surface.
What is scum?
Scum is a layer of dirt or impurities that forms on the surface of a liquid, typically water. It can consist of various substances such as oils, proteins, or minerals, and is usually removed to improve the cleanliness or quality of the liquid.
What effect does hard water have on soap?
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)
Which are best to use soaps or soapless detergents explain your answer?
Soapless - they dont form an insoluble scum with hard water dude
What do you mean by the water is hard and water is soft?
Hard water has natural ions dissolved in it. It keeps shampoo for forming suds, it forms soap scum, and it leaves calcium and other deposits in your plumbing. Soft water doesn't have these ions.
