question_answer 64)

  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:

  Sodium hydroxide () is commonly used base and is hygroscopic, that is, it absorbs moisture from the atmosphere and becomes sticky. Thus, base B is(sodium hydroxide).It is also a by-product of chlor-alkali process. The acidic oxide reacts with base to give salt and water. Ifis the acidic oxide taken, then the following reaction takes place with 'B'. Such reaction is called neutralization reaction.
