What is meant by the term pH of a solution? The pH of rain water collected from two cities A and B was found to be 6 and 5 respectively. The water of which city is more acidic?

Text Solution

Verified by Experts

pH of a solution is a measure of the `H^+` ion concentration in a solution. Lesser the pH , more acidic is the solution. Thus, rain water of city B is more acidic.
