Question

From the following:
pure water
solution of C12H22O11 (m=0.01) in water
solution of NaCl (m=0.01) in water
solution of CaCl2 (m=0.01) in water

choose the one with the
a) highest freezing point
b) lowest freezing point
c) highest boiling point
d) lowest boiling point
e) highest osmotic pressure

Answer 1

a) pure water
b) CaCl2
c) CaCl2
d) pure water
e) CaCl2

Answer 2

The freezing-point depression of a 0.091-m solution of CsCl is
0.3208C. The freezing-point depression of a 0.091-m solution
of CaCl2 is 0.4408C. In which solution does ion association
appear to be greater? Explain
