Question

How many moles of KOH are needed to neutralize 1.5 moles of H2SO4 ​

Answer 1

Answer:

1.5 moles of H₂SO₄ needs 3.0 moles pf KOH to be neutralized.​

Explanation:

• KOH is dissociate according to the equation:

KOH → K⁺ + OH⁻.

• H₂SO₄ is dissociated according to the equation:

H₂SO₄ → 2H⁺ + SO₄²⁻.

So, every 1.0 mole of KOH produces 1.0 mol of OH⁻.

While, every 1.0 mole of H₂SO₄ produces 1.0 mol of H⁺.

Thus, every mol of H₂SO₄ needs 2.0 moles of KOH to be neutralized.

So, 1.5 moles of H₂SO₄ needs (2 x 1.5 mol) = 3.0 moles pf KOH to be neutralized.​
