Natalie Caruso Chemistry – 241-602 Determining the solubility of an Unknown Salt at Various Temperatures Dr. Kahyaoglu 1/30/18
Page 14 #4. A student collected the following temperature-solubility data for ammonium chloride (NH4Cl) dissolved in water. Mass of sample, g 2.33 Total volume of water Added, mL _________________________________________________________________________________________________ 3.00 3.58 4.24 4.66 5.68 6.13 7.06 7.77 (1)Calculate the solubility of NH4Cl, in grams of NH4Cl per 100 mL water, for each saturation temperature. Enter these solubilities on the data table above. Saturation Temperature, C Solubility, grams of salt per 100 mL, water 98.0 80.0 61.0 51.0 30.0 22.0 10.0 1.00 77.7 3.00 4.24 4.66 5.68 6.13 7.06 7.77
(2) Prepare a solubility- temperature curve for NH4Cl on the graph paper on the next page.
(3)Estimate the solubility of NH4Cl at 40 C from the solubility- temperature curve you prepared in (2) a. I estimated the solubility of NH4CL at 40 C to be 76 g/100 mL.
