The pH of a 0.10M KOH solution is:
14.10.
13.00.
1.00.
0.10.
The ionization of water at room temperature is represented by:
2H2O ⇌ 2H2 + O2.
2H2O ⇌ H3O⁺ + OH⁻.
2H2O ⇌ H2 + 2OH⁻
H2O ⇌ 2H⁺ + O₂²⁻.
When the [H3O⁺] in a solution is increased to twice the original concentration, the change in pH could be from:
8.5 to 6.5.
2.0 to 4.0.
1.7 to 1.4.
5.0 to 2.5.
Calculate the [H3O⁺] in a 0.010 M solution of Sr(OH)2.
1.0 x 10-12 M.
2.0 x 10⁻² M.
5.0 x 10-13 M.
1.0 x 10⁻² M.
