The reaction between an acid and a base produces salt and water This is known as neutralization reaction. In general, HA + MOH ---> MA + H2O

Where HA is the acid, MOH the base and MA is the salt produced.

Hence, in order to make the respective salts, the acid base pairs that are needed to react are enumerated below:

  1. Hydrochloric acid and Calcium hydroxide/ oxide
  2. Phosphoric acid and Potassium hydroxide
  3. Sulfuric acid and Sodium hydroxide
  4. Nitric acid and Magnesium hydroxide/oxide
  5. Hydrochloric acid and cupric hydroxide/oxide
  6. Sulfuric acid and Potassium hydroxide
