Question

a neutralization reaction between koh (aq) and h₂so₄ (aq) would give which two products?
○ h₂o (l) and kso₄ (aq)
○ so₂ (g) and kh₂ (g)
○ h₂o (l) and h₂s (g)
○ h₂o (l) and k₂so₄ (aq)
○ none of the above

Explanation:

Step1: Identify reactants' ions

KOH(aq) → K⁺(aq) + OH⁻(aq); H₂SO₄(aq) → 2H⁺(aq) + SO₄²⁻(aq)

Step2: Balance neutralization

2OH⁻ + 2H⁺ → 2H₂O(l); K⁺ and SO₄²⁻ form K₂SO₄(aq)

Step3: Check balanced equation

2KOH(aq) + H₂SO₄(aq) → K₂SO₄(aq) + 2H₂O(l)

Answer:

D. H₂O (l) and K₂SO₄ (aq)
