[OH-]=1*10^-5M
Next question Solution A has a pH of 5 and solution B has a pH of 6.2 which solution is more acidic? What's is the [H3O+] in solution A? calculate ph of each : [H3O+]=1*10^-4M
[OH-]=1*10^-5M
Next question Solution A has a pH of 5 and solution B has a pH of 6.2 which solution is more acidic? What's is the [H3O+] in solution A? calculate ph of each : [H3O+]=1*10^-4M
[OH-]=1*10^-5M
Next question Solution A has a pH of 5 and solution B has a pH of 6.2 which solution is more acidic? What's is the [H3O+] in solution A?

Explanation / Answer

What is the pH of a solution whose [H3O+] is 1 X 10-4 M?

[H3O+] = - log(1 x 10-4)
[H3O+] = - (4)
[H3O+] = 4

What is the pH of a solution whose [H3O+] is 1 X 10 -5 M?
[H3O+] = - log(1 x 10-5)
[H3O+] = - (5)
[H3O+] = 5

Solution A has a pH of 5 will be more acidic than solution B has a pH of 6.2.

[H3O+] in solution A

pH= -log^10[H3O+]

[H3O+] = 10(-pH)

[H3O+] = 10-5 M
