How to Dispose of Hydrochloric Acid | Sciencing

Hydrochloric acid, also known as muriatic acid, the water-based solution of hydrogen chloride, is a highly corrosive acid. It is used to make batteries and fireworks, make gelatin and process sugar, but it is also produced naturally in the stomach to aid digestion as gastric acid. You must dispose of hydrochloric acid as hazardous waste by taking all necessary safety precautions, but the exact method varies by state. Contact your local officials to find out the hydrochloric acid disposal rules i
