How many moles of calcium hydroxide, ca(oh)2, are needed to neutralize 2 moles of sulfuric acid, h2so4?

To neutralize the 2 moles of H₂SO₄, 2 moles of Ca(OH)₂ are needed.

Neutralization reactions are those reactions in which acid and base react with each other to neutralize the solution.

Neutralization reaction for Ca(OH)₂ and H₂SO₄ are written as follow:

Ca(OH)₂ + H₂SO₄ → CaSO₄ + 2H₂O

According to the stoichiometry of the above reaction it is clear that 1:1 moles or equal moles of Ca(OH)₂ & H₂SO₄ react to neutralize each other.

Hence, 2 moles of calcium hydroxide are needed to neutralize 2 moles of sulfuric acid.
