O A mixture consisting of only chromium(III) bromide (CrBr3) and aluminum bromide (AlBr3) weighs 1.1218 g. When the mixture is dissolved in water and an excess of silver nitrate is added, all the bromide ions associated with the original mixture are precipitated as insoluble silver bromide (AgBr). The mass of the silver bromide is found to be 2.2708 g. Calculate the mass percentages of chromium(III) bromide and aluminum bromide in the original mixture. Mass percent CrBr3 = Mass percent AlBr3: = % %

A mixture of hydrochloric and sulfuric acids is prepared so that it contains 0.575 M HCl and 0.145 M H2SO4. What volume of 0.68 M NaOH would be required to completely neutralize all of the acid in 466 mL of this solution?
Sodium thiosulfate, Na2S203, is an important reagent for titrations. Its solutions can be standardized by titrating the iodine released when a weighed amount of potassium hydrogen iodate, KH(IO3)2 (389.912 g/mol), is allowed to react with excess potassium iodide in acidic solutions. The net ionic equations are: 8. I0; + 51+ 6 H* → 3 I2 + 3 H2O I + 2 S20; → 21+ S406² production of iodine from KH(IO;)2: 2- titration of iodine: What is the molarity of a sodium thiosulfate solution if 34.29 mL are required to titrate the iodine released from 0.1847 g of KH(IO3)2?
Zinc and magnesium react with hydrochloric acid to produce the metal chlorides and hydrogen gas. A 10.00 gram sample of a mixture of Zn and Mg was with the stoichiometric quantity of HCl. The reaction mixture was then reacted with 156 ml of 3.00 M silver nitrate to produce the maximum quantity of silver chloride. First, determine the % magnesium in the mixture; then, if 76.0 ml of HCl was added, what was the molarity of the HCl?
