Potassium carbonate is frequently used in the production of cocoa powder, and like sodium bicarbonate, is easily dissolved in water. Write the balanced reaction between potassium carbonate and acid to produce carbon dioxide.

 

Answer:

The balanced reaction between potassium carbonate ( K₂CO₃ ) and acid to produce carbon dioxide are,

i) When potassium carbonate ( K₂CO₃ ) react with sulfuric acid ( H₂SO₄ ),

K₂CO₃ + H₂SO₄ ------> K₂SO₄ + CO₂ + H₂O

ii) When potassium carbonate ( K₂CO₃ ) react with nitric acid ( HNO₃ ),

K₂CO₃ + 2 HNO₃ --------> 2 KNO₃ + H₂O + CO₂

iii) When potassium carbonate ( K₂CO₃ ) react with hydrochloric acid ( HCl ),

K₂CO₃ + 2 HCl ----> 2 KCl + CO₂ + H₂O
