Rolf prepares four solutions using different solutes as shown in the table below.
Solution
Preparation
Solubility of the solutes
A
Rolf added 20 g of solute to 100 g The solute in solution A has a
of water and mixed the solution solubility of 37 g/100 g H20 at 20°C!
B
Rolf added 10 g of solute to 100 g The solute in solution B has a
of water and mixed the solution. solubility of 10 g/100 g H20 at 20°C.
С
Rolf added 65 g of solute to 100g The solute in solution C has a
of water, mixed the solution, and
then heated the solution,
solubility of 32 g/100 g H20 at 20°C
D
Rolf added 7 g of solute to 100 g
of water, mixed the solution, and
then heated the solution
The solute in solution D has a
solubility of 4 g/100 g H20 at 20°C.
