16! What weight of sample which contains 56.15 per cent Cl was taken for analysis if the precipitated AgCl weighed 0.5017 g? Ans. 0.2210 g.

Name: Date: b) How many grams of AgCl are precipitated? Prelaboratory Assignment: Analysis of an Unknown Chloride 1.) A sample containing 0.175 g of Cl- is dissolved in 50 mL of deionized H2O. The solution is titrated to the equivalence point with a AgNO3 solution. The final volume of the titrated sample is 75 mL a) What is the concentration of the AgNO3 solution? Section: 2.) A student wishes to determine the mass percentage of barium in a 2.016 g sample. The student titrated the sample with 20 mL of 0.20 M H2SO4, producing a BaSO4 precipitate. a) How many moles of BaSO4 were formed in the titration? b) What was the mass of barium present in the original sample? c) What was the mass percent of barium in the original sample? 3) An unknown sample weighing 0.2583 g is titrated to the end point with 47.28 mL of a 0.10 M AgNO3 solution. What is the weight percent of Cl- in the sample?

A 0.5008 g sample of a pure soluble bromide compound is dissolved in water, and all of the bromide 1on is precipitated as AgBr by the addition of an excess of sılver nitrate. The mass of the resulting AgBr is found to be 0.8881g. What is the mass percentage of bromine in the original compound? Submit Answer Retry Entire Group 9 more group attempts remaining 近。 23 69
