Question

write a net-ionic equation and to include charges and physical states as appropriate...

NaI and H2SO4

Answer 1

A balanced Molecular reaction is

H₂SO₄ (aq) + 2 NaI (aq) Na₂SO₄ (aq) + 2 HI

Of the prduct formed, only HI is weak electrolyte and rest all are strong electrolyte.NaI and H2SO4 are both strong electrolytes and ionizes to full extent.

NaI (aq) Na⁺ (aq) + I^- (aq)

H₂SO₄ (aq) 2H⁺ (aq) + SO₄^2-(aq)

H₂SO₄ (aq) is a diprotic acid hence in balanced reactio equation 2 moles of NaI would react with 1 mol H₂SO₄ (aq) fully.

Ionic equation is,

A balanced Molecular reaction is

2H⁺ (aq) + SO₄^2-(aq) + 2 Na⁺ (aq) + 2 I^- (aq)   2 Na⁺ (aq) + SO₄^2- (aq) + 2 HI

On cancelling common ions we get,

2 H⁺ (aq) +  2I^- (aq)    2 HI

Is the net ionic equation.
