- The Handbook of Chemistry and Physics (http://openstaxcollege.org/l/16Handbook) gives solubilities of the following compounds in grams per 100 mL of water. Because these compounds are only slightly soluble, assume that the volume does not change on dissolution and calculate the solubility product for each. (a) BaSeO4, 0.0118 g/100 mL. (b) Ba(BrO3)2H2O, 0.30 g/100 mL. (c) NH4MgAsO46H2O, 0.033 g/100 mL. (d) La2(MoO4)3, 0.00179 g/100 mLA sample solution contains two unknown ions.

- Iron (55.845 g/mol) can be determined gravimetrically by precipitation as Fe(OH)3 (106.867 g/mol) and subsequent inflammation of the precipitate to convert it to Fe2O3 (159.69 g/mol). A 0.7873 g sample to be analyzed was weighed and transferred to a 400 mL beaker, where it was dissolved in 50 mL of H2O and 10 mL of 6M HCl. Then 2 mL of concentrated HNO3 was added to the solution. After boiling to remove excess HNO3 and nitrogen oxides, the solution was diluted to 200 mL, brought to boiling, and Fe(OH)3 was precipitated by the slow addition of 1:1 NH4OH solution until an odor of NH3 was detected (indicating the presence of excess NH3 in the medium). The solution was left in a water bath at 80 ºC for 30 min at rest. The precipitate was then filtered and washed with several portions of hot 1% m/v NH4NO3 until no Cl– was detected in the wash water. Finally, the precipitate was ignited at 500-550 °C, then left in a desiccator to cool and weighed as Fe2O3, resulting in a mass of 0.4512 g.…We have 4 test tubes filled with aqueous solution, one of which is definitely yellow. Use the information below to determine the composition of the solutions. Give the name of the cation and anion of the compunds! (there will be 4) Upon pooling of the contents of tubes 1 and 2, a white precipitate is formed which dissolves not in nitric acid but in ammonia. A yellow precipitate forms when the contents of tubes 1 and 3 are combined. When the contents of tubes 1 and 4 were combined, a brown precipitate formed. The solution turns brown when the contents of tubes 2 and 3 are combined. A yellow precipitate forms when the contents of tubes 1 and 3 are combined. When the contents of tubes 2 and 4 were combined, a reddish-brown, gelatinous precipitate formed which did not dissolve in excess reagent. No change is made when the contents of tubes 3 and 4 are pooled. Aqueous solutions of some tubes give a positive reaction to potassium and nitrate ions and must not contain sodium ions.A 0.8000-g sample of iron ore containing 21.00% Fe is analyzed gravimetrically. If the final precipitate (assumed to be Fe,03) contains 20.0 mg of Al,O3 by mistake, what percentage of Fe does the analyst find?
- 6. The potassium in the 3.0 ml plasma sample was determined by precipitating the potassium as potassium phosphotungstate, K,PW12040- From the given amount of sample, 16.36 mg of precipitate was formed. In order to check the reliability of the determination, the analyst decided to run a reagent blank. A reagent blank is done with all the reagents and steps except for the presence of the sample. The reagent blank gave 0.12 mg of precipitate. Using the data given, calculate % K and ppm K in the plasma sample. (K = 39.10 g/mol; P = 30.97 g/mol; W = 183.84 g/mol; O = 16.00 g/mol)The colorless solution of an unknown solid turned red litmus blue. No odor was noted upon adding NaOH. A gray-white precipitate formed upon adding AgNO3 and a white precipitate formed upon adding Pb(NO3)2 . The flame test gave a violet color, and bubbles formed after adding HCL. identify the unknown from the list of possibilities in the Introduction to this experimentIdentify the type of coprecipitation that occurred in the following situation. (a) The precipitation of bulky precipitates (e.g. MgNH4PO4) traps significant amount of the solution in the crystalline precipitate. ____________ (b) The formation of equimolar replacement (Al, Fe) 203 during the precipitation of hydroxides in a solution containing A13+ and Fe3+ _____________ (c) The coprecipitation of soluble ions (e.g. Na+ and CI) in the solution because of the absorption of electrolytes by colloidal precipitates. _____________ (d.)

- 15. Victoria added 6 M HCl to a sample of the unknown, containing at least one of the Group I cations. A large amount of light-colored precipitate formed. The precipitate was separated from the supernatant liquid and was found to be insoluble in hot water. The colorless supernatant liquid was separated from the precipitate and after cooling and adding K2CrO4, no precipitate resulted. The separated precipitate dissolved completely after adding 6M NH3. A white precipitate was formed, upon addition of 6M HNO3. What cation(s) may be present in the sample? a. Pb2+ b. Ag* c. Hg,2+ d. Ag*, Hg,2* e. Pb²*, Ag*In gravimetric methods of analysis, the size and kind of precipitate formed plays an important role on the accuracy of the results obtained.
