Question

Write a balanced equation for the reaction of anhydrous sodium carbonate and hydrochloric acid, and a balanced equation for the dehydration of sodium carbonate.

Answer 1

balanced equation for the reaction of anhydrous sodium carbonate and hydrochloric acid :

Na₂CO₃ (s) + 2 HCl (aq) $\rightarrow$ 2 NaCl (aq) + CO₂ (g) + H₂O (l)

balanced equation for the dehydration of sodium hydrogen carbonate :

2 NaHCO₃ (s) $\rightarrow$ Na₂CO₃ (s) + CO₂ (g) + H₂O (l)
