Question

Which of the following statement(s) is/are correct?

$\left(a\right)$ Incomplete neutralization of sodium hydroxide with sulphuric acid gives rise to base salt.
$\left(b\right)$ Incomplete neutralization of aluminium hydroxide with sulphuric acid can give rise to an acidic salt and two basic salts.
$\left(c\right)$ Incomplete neutralization of calcium hydroxide with sulphuric acid can give rise to an acidic and a basic salt.
$\left(d\right)$ Incomplete neutralization of cupric hydroxide with nitric acid gives rise to a basic salt.

• A. Only $b$
• B. Only $d$
• C. $a$ and $b$
• D. $c$ and $d$

Answer 1

Answer: (B)

Only $d$

Incomplete neutralization of cupric hydroxide with nitric acid gives rise to a basic salt.
$Cu(OH{)}_2+HN{O}_3\to Cu(OH)N{O}_3+H_{2}O$
The intermediate salt $Cu\left(OH\right)N{O}_3$ has $O{H}^{-}$ion, hence it is a basic salt.
