what are the two formulae of soap and detergent?
Asked by himanshi.updel | 04 Nov, 2018, 06:22: AM
answered-by-expert Expert Answer
  • Types of soaps:

                      i.        Hard soap is a sodium salt of fatty acids. Hard soaps are used for washing clothes.

                     ii.        Soft soap is a potassium salt of fatty acids. It does not cause skin irritation and is hence used for bathing.

 

  • The formula for soap is C17H35COONa or sodium stearate.

 

  • Synthetic detergent: A synthetic detergent is any synthetic substance, other than soap, that is an effective cleanser and functions equally well as a surface-active agent in hard or soft water. There are several methods of producing a synthetic detergent. The long chain structural units in synthetic detergents are obtained from raw materials which are mainly fats or kerosene.

CBSE 10 - Chemistry
A compound 'C' with molecular formula C2H4O2 reacts with Na metal to form compound 'R' and evolve a gas which burns with pop sound. 'C' reacts with an alcohol 'A' in presence of an acid to form a compound C2H4O2.  On addition of NaOH to 'C' it gives 'R' and water. 'S' on treatment with NaOH gives back 'R' and 'A'. Identify C,R,A,S and write down the reactions involved.
