Concept explainers
(a)
Interpretation:
The change in solubility of solid sodium chloride in water with increase in temperature has to be given.
Concept Introduction:
The solubility of ionic and molecular solids increases with increase in temperature, whereas the solubility of gas decreases with increases in temperature.
(b)
Interpretation:
The change in solubility of solid sodium chloride in water with decrease in temperature has to be given.
Concept Introduction:
Refer to part (a).
(c)
Interpretation:
The change in solubility of solid sodium chloride in water with increase in pressure has to be given.
Concept Introduction:
Henry’s law: The solubility of a gas in liquid is proportional to the partial pressure of the gas above the liquid.
For ionic/molecular solids, the solubility remains unaffected with respect to pressure.
For gases, the change in pressure would affect the solubility.
(d)
Interpretation:
The change in solubility of solid sodium chloride in water with decrease in pressure has to be given.
Concept Introduction:
Refer to part (c).

- Starch contains CC, CH, CO, and OH bonds. Hydrocarbons have only CC and CH bonds. Both starch and hydrocarbons can form colloidal dispersions in water. Which dispersion is classified as hydrophobic? Which is hydrophilic? Explain briefly.arrow_forwardIn your own words, explain why (a) seawater has a lower freezing point than fresh water. (b) salt is added to the ice in an ice cream maker to freeze the ice cream faster.arrow_forwardCooking A cook prepares a solution for boiling by adding12.5 g of NaCl to a pot holding 0.750 L of water. Atwhat temperature should the solution in the pot boil?Use Table 14.5 for needed data.arrow_forward
- Refer to Figure 13.10 ( Sec. 13-4b) to answer these questions. (a) Does a saturated solution occur when 65.0 g LiCl is present in 100 g H2O at 40 C? Explain your answer. (b) Consider a solution that contains 95.0 g LiCl in 100 g H2O at 40 C. Is the solution unsaturated, saturated, or supersaturated? Explain your answer. (c) Consider a solution that contains 50. g Li2SO4 in 200. g H2O at 50 C. Is this solution unsaturated, saturated, or supersaturated? Explain your answer. Figure 13.10 Solubility of ionic compounds versus temperature.arrow_forwardThe solubility of NaCl in water at 100 C is 39.1 g/100. g of water Calculate the boiling point of this solution.
