Lab Quiz A : Metal Reactivity, Electrolysis and Daniel Cell Labs
1a. For the Electrolysis Lab, circle anode or cathode and give the observation you make at that electrode_______________________
1b. In the space below, give the half cell that is occurring at this electrode.
2. In the Daniel/voltaic/galvanic Lab, what does it mean to have "-" V (negative voltage). Answer in the space below?
3. In the Metal Reactivity Lab, which was the most reactive metal that you found? How do you know?
4. In the Metal Reactivity Lab, pick of the chemical reactions that did occur and provide (showing all appropriate work) the following:
a. The overall chemical reaction including phases.
b. What is oxidized and what is reduced, oxidizing agent, reducing agent
c. Balance the reaction (remembering to include how many electrons,and ( ) )
5. For the Daniel/voltaic/galvanic Cell lab, please answer (on the back of this page) the following for one of the cells you made:
a. Write the oxidation half cell reaction and its Eo
b. Write the reduction half cell reaction and its Eo
c. Put a line and then give the overall balanced chemical reaction and the Ecell voltage
d. Then draw the picture of the Daniel cell from your lab notes.
