Answer» Correct Answer - A `NH_(4)Cl_((aq))toNH_(4(aq))^(+)+Cl_((aq))^(-)` `NH_(4)^(+)` ions formed, undergo hydrolysis with water to from `NH_(4)OH and H^(+)` ions. `NH_(4)OH` is a weak base and thus remains almost unionised in solution. As a result, `[H^(+)]` ions increase in solution, making the solution acidic. |
