Concept explainers
(a)
Interpretation:
Approximate molar mass of the compound has to be calculated.
Concept introduction:
Freezing point depression:
The lowering of the vapor pressure of a solvent by a solute leads to a lowering of the freezing point of the solution relative to that of the pure solvent. This effect is called as the freezing point depression. The mathematical relationship is given below.

- Fluoridation of city water supplies has been practiced in the United States for several decades. It is done by continuously adding sodium fluoride to water as it comes from a reservoir. Assume you live in a medium-sized city of 150,000 people and that 660 L (170 gal) of water is used per person per day. What mass of sodium fluoride (in kilograms) must be added to the water supply each year (365 days) to have the required fluoride concentration of 1 ppm (part per million)that is, 1 kilogram of fluoride per 1 million kilograms of water? (Sodium fluoride is 45.0% fluoride, and water has a density of 1.00 g/cm3.)arrow_forwardFor each of the following pairs of solutions, select the solution for which solute solubility is greatest. a.

- If you compare the solubilities of the noble gases in water,you find that solubility increases from smallest atomicweight to largest, Ar < Kr < Xe. Which of the followingstatements is the best explanation? (a) The heavier the gas, the more it sinks to the bottom ofthe water and leaves room for more gas molecules at thetop of the water.(b) The heavier the gas, the more dispersion forces it has,and therefore the more attractive interactions it haswith water molecules.(c) The heavier the gas, the more likely it is to hydrogenbondwith water.(d) The heavier the gas, the more likely it is to make a saturatedsolution in water.arrow_forwardA 0.100-L solution is made by dissolving 0.441 g of CaCl21s2 in water.

- To obtain a precipitate which is useful for gravimetric analysis, the analyst tries to obtain conditions to encourage crystal growth, as opposed to the formation of a colloid. Which of the following statements aids in the formation of a crystalline precipitate and the formation of a colloidal precipitate? Drag your answers to the appropriate markers. (a) The solutions are made as dilute as practical to allow crystals to form slowly. (b) The addition of strong electrolytes (e.g. NaCl or HCl) in the analyte solution, prior to the precipitation reaction. (c) After the digestion of the precipitate, the hot solution is cooled down to room temperature gradually and kept undisturbed overnight. (d) The analyst selects the precipitate of the analyte with the Ksp less than 1 x 10 -15 (e) The Relative Supersaturation value of the analyte solution should be greater than 1 million upon the addition of the precipitating reagent. formation of colloidal precipitate favored formation of crystalline…arrow_forward4.
