NaNO3

NH3

Select the solution below that is the most acidic.

In a solution that has a pH = 7.0,

[H3O+] + [OH-] = Kw

[H3O+]> [OH-]

[H3O+] = [OH-]

[H3O+]< [OH-]

Which solution is acidic?

MOH¯ = 0.0065 M

MOH¯ = 1.77 × 10¯10 M

MH+ = 1.27 × 10¯9 M

MH+ = 5.79 × 10¯10 M

Which concentration is consistent with a basic solution?

MOH- = 3.6 × 10¯9 M

MH+ = 3.2 × 10¯3 M

MH+ = 9.7 × 10¯4 M

MOH- = 3.4 × 10¯3 M
