Solution:                  pH:        Acid or Base:

0.1 M HCI                0,1

0.01 M HCI              1.1

0.1 M Na2CO3        10.3

0.1 M NaOH            13.0

0.1 M HC2H3O2      2.8

0.01 M HC2H3O2    3.6

0.1 M NaHCO3         8.2

Answer 1

If the pH  < 7, then it is an acid.

If the pH = 7, then it is neutral

If the pH > 7, then it is a base/alkali.
