Table F problems

• solubility guidelines for substances in water
• solubility ranges from very low solubility
  (basically insoluble) to very soluble
• table F use to predict if compound is soluble or
  insoluble
• left side shows soluble cmpds exceptions
• right side shows insoluble cmpds exceptions

3
predict solubility of

• LiCl
• NH4F
• Ca(HCO3)2
• BaSO4
• K2CO3
• CaCO3
• Mg3(PO4)2
• Ca(OH)2

4

• Use Table F to determine solubility of products
  formed in DR rxns

5
Predicting Products

Table G problems

• shows amount solute required for given amount of
  solvent
• Or
• shows amount solvent required for given amount of
  solute
• involves setting up a proportion

7
How much KCl will dissolve in 300 grams of
water at 50?C? Use the graph to set up a
proportion
42 g KCl X g KCl 100 g H2O 300 g
H2O
X 126g KCl
8
How much H2O is required to just dissolve 200 g
NaNO3 at 20?C?
88 g NaNO3 100 g H2O 200 g NaNO3 X g of H2O

• X 227.3 g H2O

9
Ex precipitation word problem

• A saturated solution of KNO3 is prepared in 100 g
  of water at 50?C and then cooled down to 10?C.
  How much KNO3 will precipitate?

10
88 g KNO3 in 100 g H2O at 50?C
20 g KNO3 in 100 g H2O at 10?C
88 g 20 g 68 g KNO3 precipitates
