Metals and Corrosion

Yoz,

We have finished the topic on Metals and Corrosion.

In the topic, we briefly mentioned that salt water will promote corrosion. Do you know that this simple phenomenon has applications in forensic investigation? Read this for more information.

In addition, some of you asked why in a electric cell, the displacement occurred at the less reactive electrode. E.g. when put into the lemon, effervescence occurred at the copper electrode and not at the zinc. There is an explanation offered at this website.

Enjoy!
