Examine the following information below for a electolytic cell and answer the following questions: Procedure:  Procedure: Constructing an Electrolytic Cell (convert energy to ions) 1. Obtain a 6-volt battery, electrodes, and plastic sample cup necessary to build an electrolytic cell like that shown in figure 2 below. Obtain a pH meter and set it to begin collecting data. 2. Weigh 2.0 g of solid KI. Record the mass. Transfer the solid to an Erlenmeyer flask. 3. Add 100 mL of deionized water (measure using a graduated cylinder) to the flask and swirl it until a homogeneous solution is formed. Measure and record the initial pH of this solution. 4. Transfer the 100 mL of KI solution from the Erlenmeyer flask to the plastic sample cup. Place the lid containing the electrodes on top of the sample cup. Attach wires from the batter to the electrodes. Note and record your start time. 5. Observe the electrolysis for several minutes. Record your observations at…
