- Increase
- Decrease
- \( H^+ \) increases, \( OH^- \) decreases
- Remains constant
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
As temperature increases, the ionization of water also increases. At higher temperatures, the concentration of \( H^+ \) and \( OH^- \) increases, and the pH of water decreases because pH is inversely proportional to the concentration of hydrogen ions.
Thus, the correct answer is option (2) Decrease.
