Calculate the pH of a solution whose H3O+ concentration is 1.5 x 10-13 M. Is the solution acidic, basic, or neutral?
pH = -log[H3O+]
pH = -log(1.5 x 10^-13)
Using a calculator,
pH = 12.82
Since the pH is greater than 7, the solution is basic.
a
The pH of the solution is 1.2, and the solution is basic.
b
The pH of the solution is 12.8, and the solution is acidic.
c
The pH of the solution is 12.8, and the solution is basic.
d
The pH of the solution is 1.2, and the solution is acidic.
The correct answer is:
c
The pH of the solution is 12.8, and the solution is basic.
