Questions About This Episode

What is Zinc - more useful than you realise about?

Zinc is a very useful metal that turns up in everything from sunscreen to paint, & galvanised metals to cereals, as well as brass instruments, says Prof Allan Blackman in ep 97 of Elemental. The major use of zinc is to galvanise steel in order to stop it corroding. This is because zinc oxidises more readily than iron, meaning it loses electrons more easily; chemists describe zinc as acting as the sacrificial anode, as oxidation occurs at the anode. The transition metal was well-known to the ancients who alloyed zinc and copper to make brass. Zinc is also well-known as a UV protector and turns up in sunblock (think cricketers' noses) as well as paint. You can also find zinc in car tyres, added to foods such as cereals and in anti-dandruff shampoo, says Professor Allan Blackman from the Auckland University of Technology, in episode 97 of Elemental.
