I need more help on the other chart please
Calculating pH
see chart below

2, acidic, 5, acidic

Explanation:

pH = -log[H+], where [H+] is the concentration of H+.

Using the data in the table, you can calculate the pH:

-log[1e-2] = 2

-log[1e-5] = 5

To find out whether it is acidic, basic, or neutral, use a pH scale. Anything less than 7 is acidic, anything over is basic. Knowing this, both (except the middle, which you did correctly) are acidic.
