Relative Reactivity of Alkali Metals
The reactivities of lithium, sodium, and potassium with water are compared.
Reaction of sodium and chlorine
A small piece of sodium metal is placed in a flask containing chlorine gas. Initially, no reaction is observed, but addition of a drop of water to the sodium initiates a vigorous reaction. Includes close-up replay of reaction.
Reaction of aluminum with iodine
Powdered aluminum and powdered iodine are mixed together. Adding drops of water to the mixture initiates a reaction.
Reaction of manganese with iodine
Powdered manganese and powdered iodine are mixed together. Adding drops of water to the mixture initiates a reaction.
Reaction of iron with iodine
Powdered iron and powdered iodine are mixed together. Adding drops of water to the mixture initiates a reaction.
Reaction of nickel with iodine
