We’re being asked to calculate for the pH of water at 0°C.
Recall that Kw is temperature dependent, therefore the pH of water is not equal to 7 at 0°C.
The pH and pOH of a compound determine its acidity and basicity.
▪ pH stands for the negative logarithmic function of hydronium ion concentration
▪ can be calculated using the following equation:
At 0°C the ion product constant of water, Kw, is 1.2 x 10–15. The pH of pure water at this temperature is
