9. Label the following solutions as saturated, unsaturated or supersaturated. If unsaturated, write how much more solute can be dissolved in the solution
Solution
Unsaturated, Saturated or
Supersaturated?
If unsaturated: How much more
solute can dissolve in the solution?
(a) a solution that contains 60g of NaNO,
at 30°C (in 100 mL H2O)
(b) a solution that contains 70g of NH, CI at
50°C (in 100 mL H2O)
(c) a solution that contains 20g of KCIO, at
50°C (in 100 mL H2O)
(d) a solution that contains 30g of Kl at 0°C
(in 100 mL H2O)

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
