Use the reference information given in the table above to answer the following three questions. Question 11 The electrode connected to the red wire (negative terminal on the battery) will. o produce bubbles and the pH will increase. o produce M (s) on the electrode and the pH will not change. o produce bubbles and the pH will decrease. o produce M (s) on the electrode and the pH will decrease. Question 12 The electrode connected to the black wire (positive terminal on the battery) will. o produce Z2 (s) on the electrode and the pH will not change. o produce bubbles on the electrode and the pH will decrease. o produce Z2 (s) on the electrode and the pH will increase. o produce bubbles on the electrode and the pH will increase.
