Question

the pH of a solution is a measure of the acidity or alkalinity of a solution. Water has a pH of 7 and, in general, acids have a pH less than 7 and alkaline solutions have a pH greater than 7. Find the pH of a solution with a hydronium ion concentration of 8×10−8 moles/liter.

Answer 1

7.1

Step-by-step explanation:

equation to calculate pH is

`pH=-Log_(10)(a_(H^+))=-Log_(10)(8*10^-8) = -Log_(10)(8)-Log_(10)(10^(-8))=-0.9+8=7.1`
