5
Saturation and solubility curves In this experiment we expressed concentration in units of g solute / g H 2 O Putting concentrations in g solute / g solution would be tedious and impractical See Fig 2 on pg. 316 Notice that there are solubility curves for many different substances Q - Why do temperatures range from 0-100°C A - Water is a liquid at these temperatures Solubility curves tell us how much solid will dissolve at a given temperature They also allow certain calculations…

Calculations using solubility curves Using fig 2 (pg. 316) 5. 100 g H 2 O is saturated with KClO 3 at 100°C. How much KClO 3 will come out of solution if the temperature is decreased to 48°C? How much would precipitate under the same circumstances if 350 g water were used 6. 57 g - 18 g = 39 g (57 g - 18 g) x 3.5 = 137 g (85 g - 21 g) x 1.5 = (64 g) x 1.5 = 96 g For more lessons, visit www.chalkbored.com www.chalkbored.com
