Solution

The pH of a solution:
The pH of a solution is the negative logarithm to the base 10 of the hydrogen ion concentration expressed in moles per litre.
The number 7 on the pH scale represents the neutrality of the solution.
The numbers less than 7 represent the increase in acidic properties of a solution.
The numbers greater than 7 represent the increase in basic properties of a solution.

(a) Since the solution P is a soluble acidic oxide, its pH value will be less than that of pure water.
