The combining capacity of an element is called valency. The valence electrons determine the combining capacity of an atom. The number of bonds that an atom can form as part of a compound is expressed by the valency of the element. For example- The valency of hydrogen is 1, oxygen is 2, carbon is 4, etc.

Define detergents. Write any three differences between a soap and a detergent.

Detergents are sodium salts of sulphonic acids or ammonium salts with chlorides or bromides ions, etc. The charged ends of these compounds do not form insoluble precipitates with the calcium and magnesium ions in hard water. Detergents are usually used to make shampoos and products for cleaning clothes. The difference between soaps and detergents are as follows- Soap Detergent They are sodium or potassium salts of long-chain carboxylic acids (fatty acids). They are ammonium or sulphonate salts of long-chain carboxylic acids. They are not effective in hard water and saline water and form insoluble precipitate called scum in hard water. They do not lose their effectiveness in hard water and saline water. They do not form scum. They are biodegradable. They are non-biodegradable.
