Solutions and Properties Quiz

The objectives of Unit 1 include describing the formation of different types of solutions, expressing concentration of solution in different units, stating and explaining Henry’s law and Raoult’s law, distinguishing between ideal and non-ideal solutions, explaining deviations of real solutions from Raoult’s law, describing colligative properties of solutions and correlating these with molar masses of the solutes, and explaining abnormal colligative properties exhibited by some solutes in solutions.

Mixtures containing two or more pure substances are important in daily life because their utility or importance depends on their composition. For example, the properties of different mixtures such as brass, German silver, and bronze vary, and certain concentrations of substances in solutions can have significant effects, such as preventing tooth decay or causing poisoning.

1 part per million (ppm) of fluoride ions in water prevents tooth decay, while 1.5 ppm causes the tooth to become mottled, and high concentrations of fluoride ions can be poisonous. For example, sodium fluoride, which contains fluoride ions, is used in rat poison.
