Consider the following salts. Which one(s) when dissolved in water will produce a acid solution?
$1 . R b C l O_{4} 2 . N a N O_{3} 3 . N H_{4} C l 4 . N a C l$

Question

Verified by Toppr

Answer 1

Salt of strong acid and weak base produces acidic solution
So, $N H_{4} C l \Rightarrow (N H_{4} O H + H C l)$
$S . A$
others are made from $(S . A + S . B)$ $\Rightarrow$ Neutral in $H_{2} O$
Thus, only $N H_{4} C l$ will produce acid solution.

Answer 2

Salt of strong acid and weak base produces acidic solution

So,

N H_{4} C l \Rightarrow (N H_{4} O H + H C l)

S . A

others are made from

(S . A + S . B)

\Rightarrow

Neutral in

H_{2} O

Thus, only

N H_{4} C l

will produce acid solution.

$1$ and $3$

only $3$

$1$ and $2$

$3$ and $4$

Solution

only $3$

Salt of strong acid and weak base produces acidic solution
So, $N H_{4} C l \Rightarrow (N H_{4} O H + H C l)$
$S . A$
others are made from $(S . A + S . B)$ $\Rightarrow$ Neutral in $H_{2} O$
Thus, only $N H_{4} C l$ will produce acid solution.
