Question

Complete the following reactions:
$CaC{O}_3+H_{2}O+C{O}_2\to$
$Ca(HC{O}_3{)}_2$ $+$ $\to Ca(N{O}_3{)}_2+C{O}_2+H_{2}O$

• A. $Ca(HC{O}_3{)}_2$
• B. $N{a}_{3}N$
• C. $HN{O}_3$
• D. $Ca(OH{)}_2$

Answer 1

Answer: (A), (C)

$HN{O}_3$

• When $C{O}_2$ is passed through calcium carbonate in an aqueous medium, calcium bicarbonate is formed.

$CaC{O}_3\left(s\right)+H_{2}O\left(l\right)+C{O}_2\left(g\right)\to$
$Ca\left(HC{O}_3{)}_2\right(aq)$

• Metal bicarbonates react with dilute acids to produce salt, $C{O}_2$ and $H_{2}O.$

$Ca\left(HC{O}_3{)}_2\right(s)+2HN{O}_3(aq)\to$
$Ca\left(N{O}_3{)}_2\right(aq)+2C{O}_2(g)+2H_{2}O(l)$
