in a reaction between an acid and metal carbonate nod salt is formed identify the acid and the metal carbonate write the equation also.
Answers
Answer:
(a) When an acid reacts with a metal carbonate, then a salt, carbon dioxide gas and water are produced.
Example: When dilute hydrochloric acid reacts with sodium carbonate, then sodium chloride, carbon dioxide gas and water are formed.
Na2CO3(s)+2HCl(aq)→2NaCl(aq)+CO2(g)+H2O(I)
(b).
(i) When carbon dioxide gas is passed through lime water for a short time then lime water turns milky.
Ca(OH)2(aq)+CO2(g)→CaCO3(s)+H2O(l)

(Lime water) dioxide (White ppt.)
(Make lime water milky)
(ii) When carbon dioxide gas is passed through lime water for a considerable time then lime water solution becomes clear.
CaCO3(s)+CO2(g)+H2O(l)→Ca(HCO3)2(aq)
