Question

Which of the values below could be the pH of a solution that contains 7.8 x 10-6 M H30' at 25°C.​

Answer 1

pH=5.108

Further explanation

pH shows the degree of acidity of a solution. The value between 0-14

The greater the value of H + ion concentration, the more acidic the solution is

Given

Concentration of H₃O = 7.8 x 10⁻⁶ M

Required

pH of a solution

Solution

pH= - log [H₃O⁺]

pH=-log[7.8 x 10⁻⁶]

pH=6-log 7.8

pH=5.108
