A sample is a mixture of the salts and silver nitrate, copper (II) chloride, and iron (III) chloride. When a 1.000 g sample of the mixture is dissolved in water and reacted with excess silver nitrate, 1.7809 g of precipitate forms. When a separate 1.000g sample of the mixture is treated with a reducing agent, all the metal ions in the sample are reduced to pure metals. The total mass of the metals produced is 0.4684g. Calculate the percent of each salt in the original mixture.
0.8888 g a mixture contains calcium chloride and potassium nitrate. To determine the % of each compound, silver nitrate was added to these solutions to precipitate all the chlorine in a form of silver chloride. 1.885 grams of silver chloride was precipitated, washed and dried. Calculate the % of calcium chloride in the sample.
An aqueous solution of NaF and an aqueous solution of PbCl2 react. Predict what solid will form and balance the chemical equation. If 30.6 mL of NaF solution reacted completely with excess PbCl2 to produces 10.7 g of the precipitate. What is the molarity of the original NaF solution?
An excess of barium chloride solution is reacted with 135 mL sample of sodiumcarbonate. If 7.13 g of precipitate is recovered, what is the concentration of the sodiumcarbonate solution?
Barium can be analyzed by precipitating it as BaSO4BaSO4 and weighing the precipitate. When a 0.265 gg sample of a barium compound was treated with excess H2SO4H2SO4 8.50×10−2 gg of BaSO4BaSO4 formed. What is the percentage of barium in the compound?
14.00 mL of deionized water is added to 35.00 mL 0.250 M hydrochloric acid. Calculate the molarity of the resulting solution.
4. A solution of 75 mL NazCO3 is neutralized with 67.2 mL of 0.1065 M HCI. In the another analysis, 50 mL NazCO3 is added to a solution of 25 mL Ba(NO3)2, and after the barium carbonate was precipitated, the excess of NazCO3 is neutralized with 14.8 mL of the same acid. According to this, what is concentration of barium nitrate (261.337 g/mol) in molarity and g/L?
Many chemical compounds contain impurities. Crude potassium carbonate (K2CO3) obtained from the chemical supplier is assayed for purity in the following way: 8.450 g of crude potassium carbonate is weighed out into a flask and dissolved in water. The final volume was completed to 0.500 L with distilled water. 20.00 mL sample is taken from this solution and placed in a flask. Potassium carbonate is then titrated to the equivalence point with 17.80 mL of 0.2050 M HCl solution. What is the percent purity of potassium carbonate in this sample? K2CO3 + HCl  KCl + H2O + CO2
Normally, the amount of silver nitrate required to precipitate all of the chloride in the sample is found by a trial and error process. However, to speed up the experiment, assume a sample mass of 0.1431 g, and that sample contains approximately 55.0% chloride ion by mass. From these assumptions, calculate the volume of 0.100 M AgNO3(aq) that needs to be added to precipitate all of the chloride ion. Please answer in mL. (Note: You are calculating the exact amount required and not adding 5mL in excess. In the experiment, you'd be adding an additional 5mL in excess since the chloride value of the salt may exceed 55%. Pay attention to the sig. figs. in your calculation; keep three sig. figs. in the answer.)
