Q. Which one of the following salts will produce an alkaline solution while dissolving in water?
A) $NH_{4}Cl$
B) $Na_{2}CO_{3}$
C) $NaNO_{3}$
D) $Na_{2}SO_{4}$
Explanation
(b)
$Na_{2}CO_{3}$ salt gives strong base and weak acid on dissolving in water. Hence, it produces an alkaline solution.
$Na_{2}CO_{3} + H_{2}O \rightarrow NaOH\ \ \ \ \ \ \ \ \ \ \ + \ \ \ \ H_{2}CO_{3}$
Strong base Weak acid
