Answer
hydrochloric acid
Explanation
This equation asks for two words to complete the following chemical process: sodium hydroxide + _____ → sodium chloride + water. The process described here is neutralisation. In this type of chemical reaction, an acid reacts with a base and forms a salt and water. Knowing that, we can determine the missing part of the reaction. We already have the base, which is sodium hydroxide. Thus, the missing part must be an acid which, when reacting with sodium hydroxide, will produce sodium chloride (a type of salt) and water. The corresponding acid in this case would be hydrochloric acid. Thus, the chemistry equation should read as: sodium hydroxide + hydrochloric acid → sodium chloride + water.
