Chemistry 102 Lab Practical, Spring 2019 RedOx Titration of an Unknown Iron Compound This experiment is worth half of the final exam score for this semester. It contains a laboratory procedure that is similar to the ones we've been working with all semester Part of the score for this lab practical is based on the preparations you make for the lab in advance of the experiment. When you walk into lab on Thursday night, you should have written out the following: 1) A balanced chemical equation for the oxidation of oxalic acid to carbon dioxide using potassium permanganate as the oxidizing agent, in an acid solution. This reaction can be presented as a net ionic equation 2) A calculation that predicts how many milliters of -0.020 M potassium permanganate solution you will need to titrate an -0.25 g sample of oxalic acid dihydrate, according to the balanced equation above. 3) A data table for this first titration. Your data table should look like the data tables used in the other titration experiments that we've done this semester. Read the procedure before you set up your data table, though. You should put in blanks or spaces to record data and to show sample calculations for results from the first part of the experiment. 4) A balanced chemical equation for the oxidation of iron(I) ions to iron(lI) ions using potassium permanganate as the oxidizing agent, in an acid solution. This reaction can be presented as a net ionic equation. 5) A calculation for the second part of the experiment that predicts how many milliliters of 0.020 M potassium permanganate solution you will need to titrate a 1.300 g sample of Mohr's Salt, an iron(lI)-containing compound, according to the balanced equation you write out for 4), just above
