Which of these are methods of making soluble salts?
Using a metal/insoluble base
Using an alkali
An electrolyte contains free [blank_start]ions[blank_end] which conduct electricity.
Oxidation is loss of electrons and reduction is gaining electrons.
In electrolysis, at the [blank_start]negative[blank_end] electrode, if metal and H+ ions are present, the metal ions will stay in solution is the metal is [blank_start]more[blank_end] reactive than hydrogen.
Uses of chlorine:
Cryolite is used to [blank_start]lower[blank_end] the temperature needed to melt aluminium oxide.
In electroplating, you put the thing you want to plate at the positive electrode.
