Question

The salt obtained by partial neutralization of sodium hydroxide and sulphuric acid is:

• A. basic
• B. acidic
• C. neutral
• D. weakly acidic

Answer 1

The correct option is B acidic

The salt obtained by partial neutralization of sodium hydroxide and sulphuric acid is acidic.
$NaOH+H_{2}S{O}_4\to NaHS{O}_4+H_{2}O$
In aqueous solution, $NaHS{O}_4$ will dissociate into ions.
$NaHS{O}_4\to N{a}^{+}+HS{O}_4^{-}$
In aqueous solution, $HS{O}_4^{-}$ will dissociate to provide hydrogen ions.
$HS{O}_4^{-}\to H^{+}+S{O}_4^{2-}$
