How many moles of Fe^2+ ion can be oxidized by 1.2 ×10^-2 moles MnO4 ion in the reaction between MnO4 ion and Fe^2+
lab, complete items a, b, c, and d (title, purpose, chemicals and equipment, and summary of procedure) as described on page 10 of Exp. 1 on an 8 1/2 x 11 sheet of paper. Answer the following questions on 8 1/2 x 11 sheet of paper or in your laboratory notebook if one is required by your instructor: 1. Write the balanced net ionic equation for the reaction between MnO4 ion and Fe2+ ion in acid solution. 2. How many moles of Fe2+ ion can be oxidized by 1.2 x 10-2 moles MnO4 ion in the reaction in Question 1? 3. A solid sample containing some Fe2* ion weighs 1.923 g. It requires 36.44 mL 0.0244 M KMNO4 to titrate the Fe2* in the dissolved sample to a pink end point. a. How many moles MnO4 ion are required? b. How many moles Fe2* are there in the sample? C. How many grams of iron are there in the sample? d. What is the percentage of Fe in the sample? Lab Activities: Go over the sample calculations and prelab questions with your lab instructor • Complete lab and fill in data sheet for the Standardization of Potassium Permanganate. The next data sheet, Percent Iron in Unknown Sample will be completed the following lab period. 1 |P age
