Q. 10.28 If a base is added to pure water... [FREE SOLUTION]

Chapter 10: Q. 10.28 (page 340)

If a base is added to pure water, why does the $H_{3} O^{+}$ decrease?

Short Answer

Expert verified

If a base is added to pure water, ${OH}^{-}$ ion concentration increases, therefore the equilibrium shifts in backward direction and hence the $[H_{3} O^{+}]$ ion concentration decreases.

Step by step solution

Given information

The aqueous cation $H_{3} O^{+}$ , the method of hydronium ion .The ion formed by the addition of proton to water, is known as hydronium ion. When an Arrhenius acid dissolves in water, it releases a proton to the water molecules around it, resulting in a positive ion.

Explanation

According to Le Chatelier's principle (or common ion effect), when a base is added to pure water, the concentration of ${OH}^{-}$ ions increases, causing the equilibrium to shift backwards and the $[H_{3} O^{+}]$ to appear. The ion concentration drops.

$2 H_{2} O 鈬� H_{3} O^{+} + O H^{-}$
