You will complete a series of questions that cover the Analysis of the investigation report for the lab: Analyzing for Tin(II) Chloride.
What is the concentration of a tin(ll) chloride solution prepared from a sample of tin ore?
The potassium dichromate solution is first standardized by titration with 10.00 mL of an acidified 0.03 mol/L solution of the primary standard, iron(II) ammonium sulfate-6-water. The standardized dichromate solution is then titrated against a sample of the acidified tin(II) chloride solution (You will do this step in the next question).
TITRATION OF IRON(lI) SOLUTION
(volume of K2Cr2O7(aq) required to react with 10.00 ml of 0.03 mol/L Fe2+(aq))
Final buret reading(ml)
Initial buret reading (ml)
Find the concentration of the Cr2O72-(aq) in mol/L: (give your answer to 4 decimal places)
