One potentially attractive approach to the destruction of chemical agents is chemical hydrolysis (i.e., reaction with water to form products of reduced toxicity). Because some of the reaction products are acids, a base such as lime or sodium hydroxide is generally used to neutralize the acidic products, hence, the generic description of the process ...
