answered-by-expert Expert Answer
  • Soap on mixing with water forms a concentrated solution and causes foaming.
  • The long non-polar end of soap gravitates towards and surrounds the dirt and absorbs the dust in it.
  • The short polar end with the carboxylate ion repels the water away from the dirt.
  • A spherical aggregate of soap molecules is formed in the soap solution in water and is called a micelle.
  • Thus, the soap molecule dissolves the dirt and our clothes get clean.

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.
