A 0.010 M solution of the weak acid HA has an osmotic pressure (see chapter on solutions and colloids) of 0.293 atm at 25 C. A 0.010 M solution of the weak acid HB has an osmotic pressure of 0.345 atm under the same conditions. (a) Which acid has the larger equilibrium constant for ionization HA[HA(aq)A(aq)+H+(aq)] or HB[HB(aq)H+(aq)+B(aq)]? (b) What are the equilibrium constants for the ionization of these acids? (Hint: Remember that each solution contains three dissolved species: the weak acid (HA or HB). the conjugate base (A- or B- and the hydrogen ion (H+). Remember that osmotic pressure (like all colligative properties) is related to the total number of solute particles. Specifically for osmotic pressure, those concentrations are described by molarities.)
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.
Maple syrup sap is 3% sugar (sucrose) and 97% water bymass. Maple syrup is produced by heating the sap toevaporate a certain amount of the water. (a) Describe what happens to the composition and boilingpoint of the solution as evaporation takes place. (b) A rule of thumb among maple syrup producers is thatthe finished syrup should boil about 4 C higher than theoriginal sap being boiled. Explain the chemistry behindthis guideline. (c) If the finished product boils 4 C higher than the originalsap, calculate the concentration of sugar in the finalproduct. Assume that sugar is the only solute and theoperation is done at 1 atm pressure.

Temperature of the system? Concentration of species in solution? Volume?true b. If the volume of the system decreases, do you think the system would want more gas molecules or less gas molecules in the system to relieve the "stress" on the system? Based on this, what would happen to the forward and reverse reaction rates? Why?

(If more than one compound fits the description, include all the relevant compounds by writing your answer as a string of characters without punctuation, e.g, ABC.) Without doing any calculations it is possible to determine that lead fluoride is more soluble than fill in the blank 1, and lead fluoride is less soluble than fill in the blank 2. It is not possible to determine whether lead fluoride is more or less soluble than fill in the blank 3 by simply comparing Ksp values.

A bubble of air escaping from a diver's mask rises from a depth of 163 ft to the surface where the pressure is 1.00 atm. Initially, the bubble has a volume of 10.0 mL. Assuming none of the air dissolves in the water, how many times larger is the bubble just as it reaches the surface? Use this data: 1. The density of seawater is approximately 1.025 g mL1 2. The density of mercury is 13.6 g mL 1 i times larger Use your answer to explain why scuba divers constantly exhale as they slowly rise from a deep dive. v by a factor of approximately , the volume must by a Since the pressure i factor of approximately i increase decrease Divers exhale to the amount of gas in their lungs, so it does not v to a volume rrarrthe diver's lungs.
