The normal freezing point of water is 0oC and it's freezing point depression constant is 1.86oC/m. If a 2.00 molal solution of N
a2SO4 is prepared, what is the freezing point of the mixture?

Answer:
Explanation:
The formula for the change in freezing point ΔT_f caused by an electrolyte is
1. Calculate i
Na₂SO₄(aq) ⟶ 2Na⁺(aq) + SO₄²⁻(aq)
1 mol Na₂SO₄ gives 3 mol ions.
i = 3
2. Calculate the freezing point
(a) Change in freezing point
(b) Freezing point
Answer:
The answer is -11.16°C
