Question

Which of the following solutions are acidic?

pH = 9
pH = 3
[H30+1 = 2.5 x 10-6 M.
[H3O+] = 49 x 10-10 M

Answer 1

Solutions that are acidic are the one with pH 3 and the one that has [H30+]= 2.5 x 10-6 M

Step-by-step explanation:

Acidic solutions are the one which the pH is lower than 7, the ones that have a pH higher than 7 are basic solutions.

Solutions at ph 7 are neutral.

pH = - log [H3O+]

[H3O+] = 10^-pH
