Question

Solubility of potassium chlorate at different temperatures.
Temp(0C) 20 40 60 80 100
Solubility(g/100g) 8.5 16.3 27.5 42.5 59.5


What mass of potassium chlorate will be needed to make a saturated solution of it in 50g of water at 800 C?

Answer 1

Answer:

33.49

Explanation:

Let volume of solution be V ml which contains 34.7gm of KCl and 100gm of water.

Density =(34.7+100)/V=1.3gm/ml

134.7=1.3V

V=134.7/1.3ml=103.61ml

w/V=mass of KCl in100mlof Sol

103.61ml of KCl contains 34.7g of KCl

100ml of KCl contains

103.61

34.7

×100=33.49gm100ml.
