Procedure Notes and Modifications:
Be sure to wear your safety goggles throughout the experiment. Follow the procedure as given in the lab manual. Your TA will demonstrate the proper procedure for performing a titration. Be careful with silver nitrate solutions. They will stain your skin and clothing. Be careful with potassium chromate solutions, they too will stain skin and clothing. If any solutions are spilled, rinse the area with copious amounts of water and clean up the spill. Place all waste solids in the container for waste solids. Place all waste solutions and leftover silver nitrate form your buret in the waste solutions container. DO NOT pour waste down the drain.
For Your Report:
Write and discuss balanced chemical equations for any chemical reactions that occur. Again, you can predict the results of the experiment before you even come to lab. Compare the results from the three runs. Calculate the average of the three determinations. Were your results precise? How could the precision be improved? Complete the advance study assignment for the Calorimetry experiment and attach it to your report. You will do the assignment for the Spectrum lab as a part of the report for that experiment.

Determination of an Unknown Chloride The determination of a soluble chloride salt concentration is a classic titrametric analysis. A titration involves delivering a measured amount of a solution whose concentration is known accurately (the titrant) into a solution whose concentration is not known (the titrate). The purpose of the titration is ...
The endpoint of this titration which is shown is the equivalence point and it is used to calculate the concentration of chloride present in an unknown solution. The analysis depends on the volume and no moles of known AgNO3 solution and the endpoint.

ratio of chloride : original is 0.696 : 1.00 Perform the same calculation for the potassium salt, as needed, to complete the advanced study assignment or data page. Calculate the actual mass ratio of chloride salt to original compound to determine which theoretical ratio it matches. This determines the identity of the original compound. Procedure:
The student passed the endpoint of titration when taking the final burette reading. This means he added an excess of AgNO 3 to the solution. a)The titration was carried out with 10ml of Cl - ions of unknown concentration. It required 13.89 ml of 0.02014M solution of AgNO 3. So, the concentration of Cl - was (13.89 x 0.02014/ 10)M.
