Electrolysis
What this topic asks you to be able to do
- predict which substances are released at the electrodes during electrolysis, using whether the electrolyte is molten or aqueous, where each species sits in the redox series (electrode potential) and its concentration
- state and apply the expression F = Le, which connects the Faraday constant (F), the Avogadro constant (L) and the electron's charge (e)
- calculate: (a) how much charge flows in electrolysis, from Q = It (b) the mass and/or volume of a substance set free by electrolysis
- describe how a value for the Avogadro constant is obtained through an electrolytic technique
