Question

Vinegar, CH3COOH can be used to remove limescale deposits.

Describe how vinegar can remove limescale deposits with the aid of a
balanced equation.

Answer 1

The reaction between acids in acetic acid in vinegar reacts with bases of calcium carbonate to form calcium acetate salts

Further explanation

Calcium can form deposits on the surface of equipment in contact with water in the form of CaCO₃

vinegar which contains acetic acid can break the bonds between Calcium and Carbonate that form calcium acetate

CaCO₃ + 2CH₃COOH = Ca(CH₃COO)₂ + H₂CO₃

CaCO₃ + 2CH₃COOH = Ca(CH₃COO)₂ + H₂O + CO₂
