Na 2 CO 3, on hydrolysis gives alkaline solution, as the solution contains strong base and weak acid. underset text white Na 2 CO 3 stackrel2 H 2 O longrightarrow underset text strong base 2 NaOH + underset text weak acid H 2 CO 3

Q. A white substance having alkaline nature in solution is:

$N a N O_{3}$

$N H_{4} Cl$

$N a_{2} C O_{3}$

$F e_{2} O_{3}$

$N a_{2} C O_{3}$ , on hydrolysis gives alkaline solution, as the solution contains strong base and weak acid.
$white N a_{2} C O_{3} ⟶ 2 H_{2} O strong base 2 N a O H + weak acid H_{2} C O_{3}$
