1.	A dry pellet of a common base B , when kept in open absorbs moisture and turns sticky. The compound is also a by - product of chlor - alkali process. Identify B. What type of reaction occurs when B is treated with an acidic oxide? Write a balanced chemical equation for one such solution.
Answer» Solution :Sodium hydroxide (NaOH) is a COMMONLY used base and is hygroscopic , that is , it ABSORBS moisture from the atmosphere and becomes sticky. The acidic oxides REACT with base to give salt and water. The REACTION between NaOH and `CO_2` can be given as `2NaOH + CO_(2) rarr Na_(2)CO_(3) +H_(2)O`
