A student is performing an experiment to study the properties of acetic acid. Answer the following questions :(i) Name the substance he must add to acetic acid to produce carbon dioxide. (ii) Give the relevant chemical equation for the reaction.(iii) How would he test CO2 gas in the laboratory?


(i)  The substance that must be added to acetic acid to produce carbon dioxide is sodium carbonate (Na2CO3) or sodium hydrogen carbonate (NaHCO3)

(ii)  The relevant chemical equation for the reaction is given below:
$CH_{3}COOH+NaHCO_{3}\rightarrow CH_{3}COONa+H_{2}O+CO_{2}$
OR
$2CH_{3}COOH+Na_{2}CO_{3}\rightarrow 2CH_{3}COONa+H_{2}O+CO_{2}$

(iii) The liberated CO2 (carbon dioxide) gas is passed through lime water which turns milky.
