The physical properties of a metal depend on how dense the metal is
Answer:
b. Two moles of thiosulfate anion needed to react with one mole of hypochlorite anion.
Explanation:
1. Hypochlorite with iodide
2I⁻ ⟶ I₂ + 2e⁻
<u>ClO⁻ + 2H⁺ + 2e⁻ ⟶ Cl⁻ + H₂O </u>
2I⁻ + ClO⁻ + 2H⁺ ⟶ I₂ + Cl⁻ + H₂O
2. Thiosulfate with iodine
2S₂O₃²⁻ ⟶ S₄O₆²⁻ + 2e⁻
<u> I₂ + 2e⁻ ⟶ 2I⁻ </u>
2S₂O₃²⁻ + I₂ ⟶ S₄O₆²⁻ + 2I⁻
3. Sum of the reactions
2I⁻ + ClO⁻ + 2H⁺ ⟶ I₂ + Cl⁻ + H₂O
<u> 2S₂O₃²⁻ + I₂ ⟶ S₄O₆²⁻ + 2I⁻ </u>
2I⁻ + ClO⁻ + 2S₂O₃²⁻ + 2H⁺ ⟶ I₂ + Cl⁻ + S₄O₆²⁻ + H₂O
4. Molar ratio
S₂O₃²⁻:ClO⁻ = 2:1
