(Do not reuse the acid in the beaker this should be rinsed down the sink. This work was supported by the Suh Kyungbae Foundation (SUHF) Young Investigator Award to D.K. JAMA 206, 591595 (1968). It's a precipitation reaction much like what you've probably learned before, just now in the class of organic salts, not metallic salts. In order to neutralize hydrochloric acid with sodium hydroxide, the following steps must be followed: Neutralization reactions are classified as exothermic reactions. The reaction between an acid and a base simply produces salt water, a harmless substance. In order to calculate how much sodium hydroxide is needed to neutralize hydrochloric acid, the molarity of each must be known.
