Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 (part 1 of 2) 10.0 points Which part of the complex iron compound will be analyzed in this experiment? 1. iron content 2. potassium content 3. water content 4. oxalate content correct Explanation: 002 (part 2 of 2) 10.0 points Which of the following is a good reason to use the redox titration technique for quantitative analysis? 1. The analyte can be quantitatively re- duced or oxidized. 2. All of these reasons are correct. correct 3. The redox titration is similar to the acid- base titration technique that you already have experience with. 4. We are doing a quantitative analysis, and titration is a very precise quantitative analysis technique. Explanation: 003 (part 1 of 2) 10.0 points What are the two principle reactants in the chemical reaction that will be used as a basis for the titration? 1. C 2 O 2- 4 and H + 2. Fe 3+ and MnO- 4 3. C 2 O 2- 4 and MnO- 4 correct 4. MnO- 4 and H + Explanation: 004 (part 2 of 2) 10.0 points Which is the titrant and which is the analyte in our redox titration? 1. C 2 O 2- 4 is the titrant and MnO- 4 is the analyte 2. MnO- 4 is the titrant and H + is the ana- lyte 3. MnO- 4 is the titrant and C 2 O 2- 4 is the analyte...
