According to the explanation given in our previous session, in this question, we have to use the pH formula again in order to find the pH of these 2 solutions:
Solution 1:
pH = -log [7.2*10^-9]
pH = 8.14, which is above 7, therefore BASIC
Solution 2:
pH = -log [4.4*10^-11]
pH = 10.36, which is above 7, therefore BASIC
