Question

Which is the strongest base?

[H+] = 10^-9
[H+] = 10^-11
[H+] = 10^-10
[H+] = 10^-12

Answer 1

The answer to your question is: [H+] = 10⁻¹²

Step-by-step explanation:

Remember that pH = -log [H+], then, in this exercise we need to calculate the pH of the substances and compare the results, the one which the higher value will be the strongest base.

a) [H+] = 10^-9 pH = -log[10⁻⁹] = 8

b) [H+] = 10^-11 pH = -log[10⁻¹¹] = 10

c) [H+] = 10^-10 pH = -log[10⁻¹⁰] = 9

d) [H+] = 10^-12 pH = -log[10⁻¹²] = 11 This is the strongest base
