Lab skills

So, you have taught your classes everything they need to know about moles and molarities.

You have run over the IA criteria with them and have talked in depth about data presentation and errors. What next?

Well, you are ready for a lab session – making a standard solution (of acid?) and then a titration to work out the concentration of an unknown alkali.

There is just one problem – some students have never carried out a titration beofre. What do you do – well, (obviously) you teach them how to do this but you could ask them to watch the following video beforehand – just to help them along their way.

Enjoy!
