Homework Answers
Water is polar solvent, thus ionic compounds or polar compounds are easily soluble in water due to ionic-dipole interaction. Among the given compounds NaF and KBr are ionic compounds and ethanol is polar solvent. So, these three are soluble in water.
Heptane and pentane are insoluble in water.

Carbon dioxide dissolves in water to form carbonic acid, which
is primarily dissolved CO2. Dissolved CO2 satisfies the equilibrium
equation The acid dissociation constants listed in most standard
reference texts for carbonic acid actually apply to dissolved CO2.
For a CO2 partial pressure of 1.8×10–4 bar in the atmosphere, what
is the pH of water in equilibrium with the atmosphere? (For
carbonic acid Ka1 = 4.46× 10–7 and Ka2 = 4.69× 10–11).

A table of enthalpies of solvation in water is given below for various substances at 298 K and 1 bar. Which of these substances release heat when dissolved (exothermic) and which absorb heat when dissolved (endothermic)? If you dissolved 5 mol of each of these in water at 298 K, how much heat would be absorbed or released? Assume the enthalpy of solvation is constant for all solute concentrations. Calculate the temperature change if 1 L of liquid water at...
