Answer 1

Baking soda can be suggested as a remedy to the person suffering from acidity. Acidity is caused by the production hydrochloric acid in the stomach, and excess of acid causes pain and burning. Baking soda (NaHCO₃) is basic in nature and it neutralizes the HCl produced in the stomach, bringing relief. 
NaHCO₃ (s)+ HCl (aq) → NaCl (aq) + CO₂ (g)+ H₂O(l)
