A student dissolved 221.5 grams of cesium chloride in 100.0 grams of 90 °C water. The student then cooled that solution to 20 °C . That cooled solution formed a solid (or "precipitate"), and after separating and drying this solid the student found that the solid weighed 32.3 grams. What is the solubility of cesium chloride in water at 20 °C ? calculate your answer as grams of cesium chloride per 100 grams of water.
Homework Answers
The maximum amount that can be dissolved in the solvent of a substance is called solubility of that substance.
Therefore, the amount of calcium chloride left in water at 20 ° C in 100grams is called the solubility of calcium chloride per 100 grams of water
So,
Solubility of calcium chloride =( total amount of calcium chloride dissolved in 100grams water )- (precipitate amount of calcium chloride at 20°C)
Solubility of Calcium chloride = 221.5g - 32.3g
Solubility of calcium chloride = 189.2g
Hence, solubility of calcium chloride at 20°C per 100 grams of water is 189.2g
Add Answer to:
A student dissolved 221.5 grams of cesium chloride in 100.0
grams of 90 °C water. The...
