Experiment IS Advance Study Assignment: Analysis of an Unknown Chloride 47 159-:10- l. A student performed this experiment and obtained the following concentration values: 7. 5360 x10+ M 75477 Ã 10-M. and 7.5411Ã10-M. a. What is the mean concentration? 4 3 b. What is the standard deviation of these results? 2 A 10.00 ml. diluted chloride sample required 44.89 mL. of 0.01982 M AgNO, to reach the Fajans end point. How many moles of Ci ion were present in the sample? (Use Eqs. 2 and 3.) a. moles Cr b. What was the concentration of chloride in the diluted solution? 3. How would the following errors affect the mass percent CI obtained in Question 2e? Give your reason- ing in each case. a. The student read the molarity of AgNO, as 001982 M instead of 0.01892 M. b. The student was past the end point of the titration when he took the final buret reading. 113
