Why does the pH of pure water decreases with the increase in temperatu

1.	Why does the pH of pure water decreases with the increase in temperature?
Answer» And vice versa Ionisation of water which increases H+ concentration as well as OH- concentration is an endothermic process . As temperature decrease concentration of ions decrease so negative log in H+ increase so on increase. Total Ph of pure water is 100 degree and increase 6.14 in temperature
