ZAn electrolytic cell was constructedfrom zinc and copper half-cells. Theequation of the reaction is shownbelow. *Zn (s) + Cu* (ag) Zn" (ag) + Cu (s)The observed voltage was found to be 1.00 V instead of the standard cell potential, E of 1.10V.Which of the following accounts for this observation?A. The solutions in the half-cells had different volumes.B. The copper clectrode was larger than the zinc electrode.C. The Zn solution was more concentrated than the Cu2* solution.D. The Zn electrolyte was ZnSO4, while the Cu electrolyte was Cu(NO)2 2.

In the reaction being studied in this lab, solutions of hydrogen peroxide, H2O2, and potassium permanganate, KMnO4, will be combined in acidic solution. KMnO4, will be used as the titrant to analyze the concentration of hydrogen peroxide in a drugstore bottle. The KMnO4 solution is purple in color, as it is added to the hydrogen peroxide solution, it reacts with the H2O2 to produce colorless Mn2+, and thus the color will fade in the flask. When all the H2O2has been used up, the last drop of potassium permanganate that is added will keep its color. The endpoint of the titration is the point at which the last drop of KMnO4 added to the solution causes it to turn pink. The balanced equation for the reaction in this lab is: 2MnO4‒(aq) + 5H2O2(aq) + 6H+(aq) à 2Mn2+(aq) + 5O2(g) + 8H2O(l) 1. What is the titrant in this lab? 2. What is the analyte in this lab? 3.

Part IV Cabbage Juice Indicator Chop cabbage into small pieces until you have about 2 cups of chopped cabbage. Boil for at least ten minutes to allow time for the color to leach out of the cabbage. Allow it to cool for 15 min • Filter out the plant material to obtain a red-purple-bluish colored liquid. 1. Add 1-2 drops of cabbage juice into a small bowl 2. Add 3-5 drops of vinegar into the bowl with the cabbage juice 3. Observe Is this a chemical change or physical change? Explain? Store the excess cabbage juice in your refrigerator, you will need them for future experiments.
