CIE IGCSE Chemistry/Edexcel GCSE/MYP chemistry /Reactions at the electrodes./Electrolysis/Lesson -3

Reactions at electrodes#Concepts with cambridge./ What does electrolysis of these molten compounds give?
sodium chloride, NaCl
aluminium oxide, Al2 O3
calcium fluoride, CaF2
lead sulfide, PbS
Name the products at each electrode, when these aqueous
solutions are electrolysed using inert electrodes:
a concentrated solution of magnesium chloride, MgCl2
concentrated hydrochloric acid, HCl
a dilute solution of copper(II) sulfate, CuSO4
Oxidation Is Loss of electrons,
Reduction Is Gain of electrons.
Reactivity series
