Concept explainers
(a)
Interpretation:
The change in solubility of helium 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 helium in water with decrease in temperature has to be given.
Concept Introduction:
Refer to part (a).
(c)
Interpretation:
The change in solubility of helium 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 helium in water with decrease in pressure has to be given.
Concept Introduction:
Refer to part (c).

- In 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_forwardStarch 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_forwardn oil spill spreads out on the surface of water, rather than dissolving in the water. Explain why.arrow_forward
- What mass of a 4.00% NaOH solution by mass contains 15.0 g of NaOH?arrow_forwardRefer 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_forward
