Question

There is loss in weight when mixture of $L{i}_{2}C{O}_3$ and $N{a}_{2}C{O}_3\cdot 10H_{2}O$ is heated strongly. This loss is due to:

• A. $L{i}_{2}C{O}_3$
• B. $N{a}_{2}C{O}_3\cdot 10H_{2}O$
• C. both (a) and (b)
• D. none of these

Answer 1

The correct option is C both (a) and (b)

$L{i}_{2}C{O}_3\to L{i}_{2}O+C{O}_2\uparrow$
$N{a}_{2}C{O}_3\cdot 10H_{2}O\to N{a}_{2}C{O}_3+10H_{2}O\uparrow$
