Answer 2

Ba(OH)2, also known as barium hydroxide, can be obtained through two methods. Here are the two methods:

Method 1: Reaction between Barium Oxide and Water

Barium hydroxide can be obtained by reacting barium oxide (BaO) with water (H2O). The chemical equation for this reaction is:

BaO + H2O → Ba(OH)2 In this reaction, one molecule of barium oxide reacts with two molecules of water to produce one molecule of barium hydroxide.

Method 2: Reaction between Barium Chloride and Sodium Hydroxide

Another method to obtain barium hydroxide is by reacting barium chloride (BaCl2) with sodium hydroxide (NaOH). The chemical equation for this reaction is:

BaCl2 + 2NaOH → Ba(OH)2 + 2NaCl In this reaction, one molecule of barium chloride reacts with two molecules of sodium hydroxide to produce one molecule of barium hydroxide and two molecules of sodium chloride.
