Question

A white solid “X” when reacts with an acid “B” in its dilute solution produces a gas which turns lime water milky. Identify “A” and “B”, and write the two equations involved.

Answer 1

X is ZnCO₃  Zinc Carbonate.

B is HCl ( hydrochloric acid)

ZnCO₃ + HCl →  ZnCl₂ + H₂O + CO₂↑( gas )

CO₂ + Ca(OH)₂ ⇒  CaCO₃ + H₂O

Answer 2

Answer:

X is ZnCO₃  

B is hydrochloric acid (HCL)

ZnCO₃ + HCl →  ZnCl₂ + H₂O + CO₂↑( gas )

CO₂ + Ca(OH)₂ ⇒  CaCO₃ + H₂O
