Chem paper 3 help!!

(1/6) > >>

thukon:
Just generally, what tests do we need to learn? Like test for sulphur dioxide other ones?

And does anyone know a chem guide website? I already know chemguide.co.uk, but thats mostly for A levels.

jkiam11:
You need to know basic tests such as oxygen and hydrogen tests and also tests for soluble ions such as zinc ion and copper ions.

thukon:
Yes but sometimes they ask tests fro random gases like sulphur dioxide. And what catalysts do we need to know? Like for decomposition of hydrogen peroxide and what else?

jkiam11:
Which paper did they ask you to test a random gas? There is nothing about identifying sulphur dioxide in the syllabus.
