reactions of metals with acids and water

React the same mass of metal

Make sure that each metal has a similar surface area (powder, granules or solid)

React each metal with the same amount of water

React each metal with salt solutions of the other metals (e.g. CuSO₄, ZnSO₄ or AgNO₃)

Which metal reacted with the most salt solutions?

Which metal reacted most vigorously?

Trap the gas with thumb on the end of the test tube

Light a splint (long thin piece of wood)

Tip test tube to horizontal (almost!)

Remove thumb and light gas, placeing splint into tube

If a "squeaky pop, it's Hydrogen (explodes)!
