Question

Chapter 12 reason ionic compounds do not dissolve well in nonpolar solvents is that A) ion-dipole interactions are too large for effective solvation to occur. B) ion-solvent interactions are not strong enough to solvate the ions in solution. C) not all cations and anions have the same magnitude of charge and therefore do not form neutral ion pairs. D) there are no forces of attraction between ions and nonpolar molecules In general, as the temperature increases, the solubility of gases in waterand the solubility of most solids in water- ." A) decreases, decreases B) decreases, increases C) increases, decreases D) increases, increases The solubility of argon in water at 25°C is 0.0150 mol/L. What is the Henry's Law constant for argon if the partial pressure of argon in air is 0.00934 atm? A) 1.40 x 10-4 mol/(L atm) B) 0.623 mol/L atm) 0 C) 1.61 mol/(L atm) D) 4.10 mol/(L atm) Answer: C What is the mole fraction of ethanol in a solution made by dissolving 14.6 g of ethanol, C,H,OH, in 53.6 g of water? Answer: 0.0964 A solution is prepared by dissolving 17.75 g sulfuric acid, HSO, in enough water to make 100.0 ml of solution. If the density of the solution is 1.1094 g/mL, what is the molality? Answer: 1.940 m H,SO,

Explanation / Answer

ANSWer 12. b)

1 reason why Ionic compounds , do not dissolve well in non polar solvents is because ion -solvent interactions are not strong enough to solvate the compound.
