Unformatted text preview: Identify the reducing and oxidizing agents. 5. Explain the purpose of starch in this experiment. 6. (a) Using a volumetric flask, a student makes 500.0 ml of Ca(NO 3 ) 2 solution by dissolving 59.47 grams of Ca(NO 3 ) 2 in distilled water. Calculate the molarity of Ca(NO 3 ) 2 in this solution. (b) The student then pipets 10.00 ml of the Ca(NO 3 ) 2 solution made in (a) into a 250.0 ml volumetric flask and adds distilled water to the mark. Calculate the molarity of Ca(NO 3 ) 2 in this diluted solution....
