Question
Acetic acid + Sodium hydrogen carbonate → (i) + Sodium acetate + WaterWhat could (i) and (ii) be?(i) + Ca (OH)2 → (ii) + WaterA.B.C.D.(i) CaCO3 ; (ii) CO2(i) H2O ; (ii) CaCO3(i) CO2 ; (ii) CaCO3(i) H2O ; (ii) CO2
Solution
The reaction between acetic acid and sodium hydrogen carbonate (baking soda) produces carbon dioxide gas, sodium acetate, and water. So, (i) is CO2.
The reaction between calcium hydroxide and carbon dioxide produces calcium carbonate and water. So, (ii) is CaCO3.
Therefore, the correct answer is (i) CO2 ; (ii) CaCO3.
