Answer» Correct Answer - C `(A)CH_(3)COONahArrunderset("Weak acid")(CH_(3)COO^(-))+underset("Strong base")(Na^(+))` (Basic) (B) `NH_(4)ClhArrunderset("Weak base")(NH_(4)^(+))+underset("Strong acid")(Cl^(-))` (Acidic) (C) `NaNO_(3)hArrunderset("Strong base")(Na^(+))+underset("Strong acid")(NO_(3)^(-))` (Neutral) (D) `CH_(3)COONH_(4)hArrunderset("Weak acid")(CH_(3)COO^(-))+underset("Weak base")(NH_(4)^(+))` (Almost neutral) May be slightly acidic or basic depending upon `pK_(a) and pK_(b)` value of acid and base. |
