A dry pellet of a common base 'B', when kept in open, absorbs moisture and turns sticky. The compound is also formed by chloralkali process. Identify B. What type of reaction occurs when B is treated with dilute hydrochloric acid. Write the chemical equation.

The compound B is sodium hydroxide. Its chemical formula is NaOH.

When sodium hydroxide is treated with dilu. HCl, it gives a salt. The reaction is:
