Two salts 'X' and 'Y' are dissolved in water separately. When phenolphthalein is added to these two solutions, the solution 'X' turns pink and the solution 'Y' does not show any change in colour, therefore 'X' and 'Y' are
  1. (X) = Na2CO3, (Y) = NH4Cl
  2. (X) = Na2SO4, (Y) = NaHCO3
  3. (X) = NH4Cl, (Y) = Na2SO4
  4. (X) = NaNO3, (Y) = Na2SO4

Solution

(a)
