An iron Oxalate salt is titrated with permanganate: 5C_2O_4^2- + 2MnO_4^- + 16 H

Question

An iron Oxalate salt is titrated with permanganate: 5C_2O_4^2- + 2MnO_4^- + 16 H^+ rightarrow 10CO_2 + 2Mn^2+ + BH_2O If 22.0 mL of a 0.010M KMnO_4 was used to reach the equivalence point in titrating the oxalate salt, how many mole of the oxalate were oxidized? 2.2 times 10^-1 5.5 times 10^-1 2.2 times 10^-1 5.5 times 10^-1 2.2 times 10^-3 In the process of analyzing the iron(III) oxalate salt for iron, the salt is titrated with EDTA. At the end point of the titration, all the iron (III) salicylate is converted to iron(III) EDTA. This end point is observed by which color change the solution? From colorless to pink from purple to yellow from purple to colorless from red to yellow Upon adding oxalic acid to a solution of ferrous ammonium sulfate and sulfuric acid, a yellow precipitate synthesis lab. This precipitate is ferrous sulfate ferric oxalate ferrous oxalate ferric sulfate ammonium You are titrating using a burette filled with 0.05 M EDTA solution. The initial reading is taken from position A. The final reading is taken from position B (see figure on the right). How many moles of EDTA were dispensed? 2.0 times 10^-2 mol 2.8 times 10^-4 mol 8.8 mol 1.1 times 10^-1mol In Experiment 1 "Synthesis of an iron Complex Salt", You added ethanol to precipitate the complex salt because___ethanol catalyzes the formation of the salt ethanol decreases the boiling point of the salt ethanol increases the melting point of the salt ethanol reduces the solubility of the salt

Explanation / Answer

1. c)2.2 E-01

2. c) from purple to colorless

3.a) ferrous sulfate

4. figure not clear remove your pencil to view burette reading

5. c) ethanol increases the melting point of salt
