Answer:

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

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
