What is pH of pure water at 70 degrees celsius?

Answer 1

The pH of pure water at 50 °C is 6.55

The dissociation constant, KW, has a value of 1.0*10−14 at 25 °C, so in neutral solution both the hydrogen ion concentration and hydroxide ion concentration are 1.0*10−7 mol/L.

The pH value of pure water decreases with increasing temperatures because the dissociation constant, KW, is depending on the temperature: 7.94*10-14. So the pH of pure water at 50 °C is 6.55. At that temperature both H+ and OH- concentrations are 2.8*10-7 mol/L

Answer 2

the ph of that water would be a 7.0

Answer 3

7
