Calculate the concentration of H ions in a 0.010 M aqueous solution of sulfuric acid. Express your answer to three decimal places and include the appropriate units.

Explanation:

     H₂SO₄      ⇄     2 H⁺    +    SO₄⁻²

    1  M                  2 M

one mole of  H₂SO₄  gives 2 moles of hydrogen ion

.010 mole of  H₂SO₄ will give 2 x .010 moles of H⁺ ion

concentration of H⁺ ion = .020 M or .020 gram - ion per litre .
