Write your observations:4 - Permanganate/Reducing AgentThe reaction is expressed in the symbolic form of the following:•MnO4- + 5 Fe+2 + 8 H+ Mn+2 + 5 Fe+3 + 4 H2O•MnO4- + 2.5 C2H2O4 + 3 H+ Mn+2 + 5 CO2 + 4 H2OIn each experiment below, 10 mls of 0.005 M potassium permanganate (KMnO4) is placed in a test tube and 5 mls of 0.5 M reducing agent is added (these solutions both contain 1 M in sulfuric acid as well). A set of eight pictures is shown for each reaction. The first test tube in each set of pictures contains the permanganate solution by itself. The other test tubes contain the permanganate solution and the reducing agent, which is either pale yellow (Fe+3) or colorless (C2H2O4). The numbers under the test tubes indicate the number of elapsed seconds.Data:Variable-4a, reducing agent- Fe+3 , temperature- room temperature (25 degrees Celsius), catalyst-none.Variable-4b, reducing agent- C2H2O4 , temperature- room temperature (25 degrees Celsius), catalyst-none.Variable-4c, reducing agent- C2H2O4 , temperature-50 degrees Celsius, catalyst-none.Variable-4d, reducing agent- C2H2O4 , temperature- room temperature (25 degrees Celsius), catalyst-MnCl2.Refer to the picture below for reference of the results.
