1 Solutions & Solubility
Q1. Where is the hydrophilic (attracted to water) region of the molecule?
Region 1
Region 2
Region 3
The three regions are equally hydrophilic
Q2. Which molecule is most soluble in water?
(Refer to associated figure for molecule structures.)
Q3. A solution of NaCl in water has a concentration of 20.5% by mass. What is the molal concen-
tration of the solution?
0.205 m
0.258 m
Q4. What is the mole fraction of water in 200 g of 89% (by mass) ethanol, C2H5OH?
0.24
0.32
0.76
QS. A mixture of 100 g of and 200 g of water is stirred at 60 C until no more of the salt
dissolves. The resulting solution is poured ofl into a separate beaker, leaving the undissolved solid
behind. The solution is now cooled to 20 solution
during the cooling?
