A solution which on treatment with hydrochloric acid produces a colourless, odourless gas which turns lime water milky is most likely to be a
- trioxonitrate (V)
- chloride
-
trioxocarbonate (IV)
- hydroxide
The correct answer is: C
Explanation
A solution containing carbonate when treated with hydrochloric acid, produces a colourless, odourless gas (carbon dioxide) that turns lime water milky.
For example, when hydrochloric acid (HCl) reacts with sodium carbonate (Na\(_2\)CO\(_3\)), it releases carbon dioxide (CO\(_2\)) gas, which is colourless and odourless.
