Which from following compounds is obtained when carbon dioxide gas bubbled through slaked lime solution?
Which from following compounds is obtained when carbon dioxide gas bubbled through slaked lime solution?
$\mathrm{CaCO}_{3(\mathrm{~s})}$
$\mathrm{CaCl}_{2(\mathrm{aq})}$
$\mathrm{CaSO}_{4(\mathrm{~s})}$
$\mathrm{NaCl}_{(\mathrm{aq})}$
Solution
When carbon dioxide is bubbled through solution of calcium hydroxide (slaked lime), water insoluble solid calcium carbonate is formed.
$\mathrm{Ca}(\mathrm{OH})_{2(\mathrm{aq})}+\mathrm{CO}_{2(\mathrm{~g})} \rightarrow \mathrm{CaCO}_{3(\mathrm{~s})}+\mathrm{H}_2 \mathrm{O}_{(\ell)}$
