Al, Cu, Cl

Al (foil)

NaCl

CuSO45H2O

HCl (10%)

Influence of combination of copper ions and chloride ions on reactivity of aluminium. A violent reaction only occurs, when both type of ions are present.

*

Al, Br

Br2

Al (foil)

HCl (10%)

Na2SO3

Reaction between bromine and aluminium, spontaneous ignition of aluminium after some delay . Aluminium foil is added to some liquid bromine.

 

Al

MnO2

Al (powder)

P (red)

Flash powder with manganese dioxide. Manganese dioxide and fine aluminium powder make a powerful flash powder. With red P it can be ignited more easily.

*

Al

P (red)

Cl2

KNO3

Al (powder)

Miniature fireworks (bright flashes) in a test tube. A mix of aluminium powder, potassium nitrate and red phosphorus is thrown in chlorine gas. This results in a very bright white flash.
