Question

If pH of solution changes from 4 to 5, then the $\text{H}_3\text{O}^+$ion concentration of solution}

• A. decreases by one times
• B. increase by one times
• C. increase by 10 times
• D. decrease by 10 times

Hint:

Each unit change in pH corresponds to a 10-fold change in $[H^+]$. Higher pH means lower $[H^+]$.

Answer 1

The Correct Option is D
