reactions of metals with acids and water

Reactions of metals with acids and water

So... how do you place metals into a series of reactivity?

• 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?

So...how do you test for Hydrogen Gas?

• 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)!
