Chapter 7, Problem 7.52E

(a) Convert the calculated mole fraction of naphthalene dissolved in toluene from Example 7.10 into molarity, assuming that the volumes are strictly additive. The density of toluene is 0.866 g / mL and density of naphthalene is 1.025 g / mL .

(b) Estimate the solubility, in g / 100 mL and molarity, of naphthalene in n -decane, C 10 H 22 , which has a density of 0.730 g / mL .

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…
