Is `pH` of solution changed in Kolbe's electrolysis.

Explanation

### Step-by-Step Solution

1. **Understanding Kolbe's Electrolysis**: Kolbe's electrolysis involves the electrolysis of the sodium or potassium salts of carboxylic acids. The general reaction can be represented as:
\[ 2RCOONa + 2H_2O \rightarrow 2R + 2NaOH + H_2 + 2CO_2 \]
In this reaction, sodium hydroxide (NaOH) is produced.
