Question

a compound ‘x’ reacts with dilute hcl and forms a gas ‘y’. then the gas ‘y’ reacts with compound ‘z’ and forms compound ‘x’ back. identify x, y and z. write all the reaction involved in it​

Answer 1

★ Answer ★

X: Sodium bicarbonate

Y: Carbon dioxide

Z: Calcium hydroxide

Reaction 1: Sodium bicarbonate (x) + Dilute Hydrochloric Acid (HCl) → Carbon Dioxide (y) + Water (H2O)

NaHCO3 + HCl → CO2 + H2O

Reaction 2: Carbon Dioxide (y) + Calcium Hydroxide (z) → Sodium Bicarbonate (x) + Water (H2O)

CO2 + Ca(OH)2 → NaHCO3 + H2O
