What is the boiling point of 1molal potassium iodide solution assuming it to be 100% dissociated? For water Kb= 0. 52K kg mol-1
373K
374.04K
1.04K
374.04°C
Van’t Hoff factor is 2
So ΔTb = i Kb m = 2 x 0.52 x 1 = 1.04K
Tb = 374.04K
Boiling point of water at 750 mm Hg is 99.63°C. How much sucrose is to be added to 500 g of water such that it boils at 100°C. Molal elevation constant for water is 0.52 K kg mol−1.
