pH is a measure of the amount of hydrogen ion activity (H+) in a solution, and therefore its alkalinity or acidity. Even though pH is a unitless value but it is not a random scale. The value is due to the activity of H+ ion in the solution. pH is described as “the negative of the logarithm of the molar hydronium-ion concentration.”

Problem 1: Find out the pH of the solution in which the concentration of hydronium ion is 8.0 ×10-8M.
Answer:
The hydronium ion concentration is 8.0 × 10-8M
pH = – log[8.0 × 10-8]
pH = 7.09
