0:00 Intro
0:51 Topic 9.8 Galvanic (Voltaic) and Electrolytic Cells
2:32 Video of an experiment involving Zn and Cu (https://bit.ly/3UP7B5B)
3:15 Question 1
7:40 Galvanic cell based on the reaction between zinc and copper
9:10 Don’t assume that the anode will always be on the left!
10:05 Examining the features of a galvanic cell
10:45 Electrons flow through the wire from the anode (where oxidation occurs) to the cathode (where reduction occurs)
11:07 The mass of the anode decreases as the cell proceeds over time (Zn(s) → Zn²⁺(aq) + 2 e⁻)
11:54 The mass of the cathode increases as the cell proceeds over time (Cu²⁺(aq) + 2 e⁻ → Cu(s))
12:37 The salt bridge is an essential component of a galvanic cell
14:00 Close-up particle view of the anode half-cell
15:06 Close-up particle view of the cathode half-cell
16:38 Mnemonic device: AN OX and RED CAT
17:16 Looking at the diagrams for Question 2
18:12 Question 2
22:00 Comparisons between a galvanic cell and an electrolytic cell
25:06 Question 3
28:15 A redox equation must be balanced in terms of both atoms and charge
29:07 Question 4
34:03 Question 5
40:09 The process of adding two half-reactions together in order to produce an overall equation for a redox equation
43:41 If a half-reaction is reversed, the sign of E° is reversed
45:00 Multiplying a half-reaction by a constant N does NOT change the value of E°
