Homework Answers
Firstly you will calculate the pH of the solution, highest pH value is most basic and lowest pH value is more acidic.
Formula pH = -log[H+]
And
[H+] [OH-] = Kw = 10^-14
1) [H+] = 10^-4
pH = -log[H+] = -log(10^-4) = 4
pH = 4
2) pH = 13
3) [H+] = Kw/[OH-] = 10^-14/(10^-3) = 10^-11
pH = 11
4) pH = 10
5) pH = 14 - pOH = 14 - 13
pH = 1
Second 2) have Highest value of pH Hence this solution is more basic.
Answer
Second option is correct
[H+] = 1 • 10^-13M
