METALS 2

Alloys and reducing series

Regular metal

• highly reactive

• not found in elemental form

• complicated to manufacture

• prefers being oxisised (ion)

• interested in acidic dissolution

Irregular metal

• far less reactive

• elemental form in nature

• less interested in acidic dissolution

• prefers being reduced (atom)

Poll

Is it "scientific enough"?

• It will do.

• Not at all.

• Make it measurable!

• Dunnoo...

The measure of metallic character

standard potential

Standard potential

• 1 mol/dm³ of metal cation solution

• metal plate

• redox half-reactions separated in space

• electricity produced
