Question

carbon dioxide gas is passed through lime water to form precipitate of calcium carbonate. write chemical balancing for the following?

Answer 1

• So when Carbon dioxide is passed through lime water, an Acid-Base reaction takes place producing salt and water. The reaction is written as, Calcium Carbonate is insoluble in water, thus forming white precipitate, making the solution appear milky. This also serves as the classic test for carbon dioxide.

CO2+Ca(OH)2==>CaCO3+H2O

Answer 2

Answer:

CO↓2 (g) + CA(OH)↓2 (aq) →CaCO↓3(s)+H↓2O.

(carbon dioxide)+(calcium hydroxide)→calcium carbonate+ water.
