Question

Calculate the number of moles of h2so4 required to neutralize 5 mole of naoh

Answer 1

Hello Dear.

Reaction for the neutralization of the H₂SO₄ and NaOH is →

H₂SO₄ + 2NaOH  ------------→ Na₂SO₄ + 2H₂O

From the Reaction,
∵ 2 moles of NaOH is neutralized by the 1 moles of H₂SO₄.
∴ 1 moles of NaOH is neutralized by the 1/2 moles of H₂SO₄.
∴ 5 moles of NaOH is neutralized by the 2.5 moles of H₂SO₄.


Hence, the number of moles of the sulphuric acid required to neutralizes the 5 moles of Sodium Hydroxide.


Hope it helps.

Answer 2

From the Reaction,

∵ 2 moles of NaOH is neutralized by the 1 moles of H₂SO₄.

∴ 1 moles of NaOH is neutralized by the 1/2 moles of H₂SO₄.

∴ 5 moles of NaOH is neutralized by the 2.5 moles of H₂SO₄.
