NH3
Select the solution below that is the most acidic.
[H3O+] = 1.0 × 10–8 M
[H3O+] = 1.0 × 10–10 M
[H3O+] = 1.0 × 10–7 M
[H3O+] = 1.0 × 10–6 M
[H3O+] = 1.0 × 10–4 M
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
The formation of nitric oxide (NO, a precursor to nitric acid) from oxygen and nitrogen is ordinarily a very slow process. What accounts for its more rapid formation in automobile exhaust?

Releases water to the atmosphere.
Purifies water by removing nitrate and sulfate ions.
What would the concentration of OH- be if the concentration of H3O+ was 1 × 10-5M? [H3O+] × [OH-] = Kw = 1 × 10-14
1 × 10-9
1 × 105
1 × 10-14
1 × 109
1 × 10-5
