Question

Describe what will happen if you mix vinegar with bicarbonate of soda and what was produced to make an irreversible change.

Answer 1

Vinegar = CH₃COOH

Bicarbonate of soda = NaHCO₃

CH₃COOH + NaHCO₃--------> CH₃COONa + CO₂ + H₂O

This is an example of irreversible change because this is a chemical reaction and the products are formed as a result of exchange of ions in the reactants.
