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.

well off of my head we know that the perfume bottle is most likely opened, or broken. i can also tell it is moving at low and high concentration because it is covering the other side of the room. what we can obtain from this information is it explains why the odor can be detected at the other side of the room.
