During the preparation of ethane by Kolbe's electrolytic method using inert electrode the `pH` of the electrolyte

Options

A. increases progressively as the reaction proceeds
B. decreases progressively as the reaction
C. remains constant throughout the reaction
D. may decrease if the concentration of the electrolyte is not very high.

Answer

A

Explanation

`2CH_(3)COO^(-)Na+2H_(2)O overset("Electrolysis")to CH_(3)-CH_(3)+2CO_(2)+H_(2)+2NaOH`
Since NaOH is fomed, the pH increases as the reaction proceeds.
