Find the H+ and (OH)- concentrations in 0.01M H2SO4

[H⁺] = 0.02 M

[OH⁻] = 5 × 10⁻¹³ M

Explanation:

H₂SO₄ also known as sulfuric acid, is a very strong acid. This means that it dissociates completely in water to form hydronium ions and sulfate ions.

H₂SO₄ ⇌ 2 H⁺ + SO₄²⁻

Because it dissociates completely in water, the concentration of H₂SO₄ is also the concentration of H⁺. So,

[H⁺] = 2(0.01) = 0.02 M

To find the [OH⁻] concentration, use the formula for the autoionization constant of water.

[H₃O⁺][OH⁻] = 1.0 × 10⁻¹⁴

[0.02 M][OH⁻] = 1.0 × 10⁻¹⁴

[OH⁻] = 1.0 × 10⁻¹⁴ ÷ 0.02

[OH⁻] = 5 × 10⁻¹³ M

In 0.01 M H₂SO₄, the H⁺ concentration is 0.02 M and the OH⁻ concentration is 5 × 10⁻¹³ M.

Hope that helps.

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)
