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

▪ pH stands for the negative logarithmic function of hydronium ion concentration
can be calculated using the following equation:
