In a redox titration, during the standardization of permanganate, how would the calculated molarity of KMnO4 be affected? 1. The KMnO4 is added too rapidly and too much KMnO4 is added, overshotting the end point. 2. Some of the solid Na2CO4 is spilled on the bench top after weighing but before beginning the titration.

For each scenario below, select the color of the solution using the indicator thymol blue during the titration. When you first add indicator to your Na2CO3 solution, the solution is basic (pH ~10), and the color is [Select] At the equivalence point for the titration, the moles of added HCI are equal to the moles of Na2CO3. One drop (or less!) past this is called the endpoint. The added HCI begins to titrate the thymol blue indicator itself. At the endpoint, the indicator color is [Select] When you weren't paying attention and added too much HCI (~12 mL extra), the color is [Select] When you really weren't paying attention and reached the second equivalence point of Na2CO3, the color is ✓ [Select] blue yellow red orange green Question 9
