Question

Predict whether the following substances will give acidic basic or neutral solution?
(i) $K_{2} {C O}_{3}$ (ii) $N a C l$ (iii) $F e {C l}_{3}$ (iv) $C u {S O}_{4}$ (v) $A l {C l}_{3}$ (vi) ${N H}_{4} C l$ (vii) ${C H}_{3} C O O {N H}_{4}$ (viii) $N a C N$ (ix) ${N a}_{2} S$ (x) ${N a}_{2} B_{4} O_{7}$

Solution

$K_{2} C O_{3}$ is a salt of strong base and weak acid so it is basic in nature.
$N a C l$ is a salt of strong base and strong acid so it is neutral in nature.
$F e C l_{3}$ is a salt of weak base and strong acid so it is acidic in nature.
$C u S O_{4}$ is a salt of weak base and strong acid so it is acidic in nature.
$A l C l_{3}$ is a salt of weak base and strong acid so it is acidic in nature.
$N H_{4} C l$ is a salt of weak base and strong acid so it is acidic in nature.
$C H_{3} C O O N H_{4}$ is a salt of weak base and weak acid so it is neutral in nature.
$N a C N$ is a salt of strong base and weak acid so it is basic in nature.
$N a_{2} S$ is a salt of strong base and weak acid so it is basic in nature.
$N a_{2} B_{4} O_{7}$ is a salt of strong base and weak acid so it is basic in nature.
