Calcium hydroxide or calcium carbonate may be worked into soil that is too acidic for plant growth. Fertilizers that develop plant growth are made by neutralizing sulfuric acid or nitric acid with ammonia gas, making ammonium sulfate or ammonium nitrate. Besides, the pH of wastewater is measured by the acid-base neutralization reaction.

Wastewater with a low pH is generally neutralized using sodium hydroxide (NaOH), lime (CaO), magnesium hydroxide (Mg(OH) 2), or calcium hydroxide (Ca(OH) 2). Wastewater with a high pH is generally neutralized with sulfuric acid (H 2 SO 4), hydrochloric acid (HC 1), or carbon dioxide (CO 2). The most common chemicals used are H 2 SO 4 and NaOH.
