Question

Potassium bicarbonate and sulfuric acid molecular equation.

a) KHCO₃ + H₂SO₄ → K₂SO₄ + H-2CO₃
b) K₂CO₃ + H₂SO₄ → K₂SO₄ + H₂CO₃
c) K₂CO₃ + HCl → KCl + H-2CO₃
d) KHCO₃ + HCl → KCl + H₂CO₃

Answer 1

The correct molecular equation for the reaction is KHCO₃ + HCl → KCl + H₂CO₃. Potassium bicarbonate reacts with hydrochloric acid to produce potassium chloride and carbonic acid.

Step-by-step explanation:

The correct molecular equation for the reaction between potassium bicarbonate and sulfuric acid is option (d) KHCO₃ + HCl → KCl + H₂CO₃.

Potassium bicarbonate (KHCO₃) reacts with hydrochloric acid (HCl) to produce potassium chloride (KCl) and carbonic acid (H₂CO₃).

It is important to note that carbonic acid is not stable and decomposes into water and carbon dioxide (CO₂) gas.
