Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.

Table sugar (C12H22O11) or urea [(NH2)2CO] can be used by road crews to melt ice on roads, but solutions of CaCl2 are generally used instead. Assuming equal costs per pound of substance, why is CaCl2 used instead of table sugar or urea?

Butylated hydroxytoluene (BHT) is used as an antioxidant in processed foods. (It prevents fats and oils from becoming rancid.) A solution of 2.500 g of BHT in 100.0 g of benzene had a freezing point of 4.880C. What is the molecular weight of BHT?
When 79.3 g of a particular compound is dissolved in 0.878 kg of water at 1 atm pressure, the solution freezes at 1.34C. If the compound docs not undergo ionization in solution and is nonvolatile, determine the molecular weight of the compound.
Sodium chloride (NaCl) is commonly used to melt ice on roads during the winter. Calcium chloride (CaCl2) is sometimes used for this purpose too. Let us compare the effectiveness of equal masses of these two compounds in lowering the freezing point of water, by calculating the freezing point depression of solutions containing 200. g of each salt in 1.00 kg of water. (An advantage of CaCl2 is that it acts more quickly because it is hygroscopic, that is. it absorbs moisture from the air to give a solution and begin the process. A disadvantage is that this compound is more costly.)

(b) Small covalent compounds dissolve in water if they can form hydrogen bonds with water molecules. (c) The solubility of ionic compounds in water generally increases as temperature increases. (d) The solubility of gases in liquids generally increases as temperature increases. (e) Pressure has little effect on the solubility of liquids in liquids. (f) Pressure has a major effect on the solubility of gases in liquids. (g) In general, the greater the pressure of a gas over water, the greater the solubility of the gas in water.
