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
