Question

What is the pH of a solution with a hydrogen-ion concentration ([H+]) of 8.7 x 10-6M? Is this acidic or basic?

Answer 1

pH = 5.06, solution is acidic

Step-by-step explanation:

pH = - log [H+]

we are given, [H+] as 8.7 x 10^-6M

Therefore;

pH = - log (8.7 x 10^-6 M)

= 5.06

pH = 5.06

But a solution with a pH of, 1-6 is acidic, while a pH of 7 is neutral and that of 8-14 is basic.

Thus; a pH of 5.06 is acidic
