Answer 1

Step-by-step explanation:

Kolbe's electrolysis: 2RCOOK+2H

2

O→R−R+2CO

2

+2KOH+H

Here in this process

Reaction occur at anode:

2CH

3

COO

∙

→2CH

∙

+2CO

2

2CH

∙

→C

2

H

as after completing the reaction solution became alkaline so pH of solution will increase.

According to reaction aq. solution of sodium acetate will form ethane.
