The word equation for neutralization is acid + base = salt + water. The acid neutralizes the base, and hence, this reaction is called a neutralization reaction. Neutralization leaves no hydrogen ions in the solution, and the pH of the solution depends on the strength of the acid.
When sodium hydroxide reacts with hydrochloric acid, the products formed are water and sodium chloride. Sodium chloride is common or cooking salt. Similarly, when magnesium hydroxide reacts with sulphuric acid, the products formed are water and magnesium sulphate. When aluminium hydroxide reacts with nitric acid, the products formed are aluminium nitrate and water.
