PAG 5.1 for LEL Y12 Chemists

Good afternoon,

12dCh and I discovered, this morning, that PAG5.1 does not work. The mixture does not separate, even following some intervention with other solvents and by trying to "salt it out". This means that we will not be doing PAG 5.1 on Wednesday or Friday and will instead be starting PAG5.2.

If you read this message before the lesson please don't complete your homework and instead we will assess the risk of the chemicals at the start of the lesson, as the DNA.

Year 12s - Enjoying DofE

Hello,

I hope you've found this post after returning from your DofE trip, but before our lesson. Could you make sure you've caught up the missing work. I've put it in the folder that is linked below. The following classes have completed the following pieces:

12cCh - L5 and L6 (including exam questions and homework x 2)
12dCh - L5 and L6  (including exam questions and homework x 2)

12eCh - you've not missed anything - hurrah!

Enjoy,
Ms Elias

12dCh - LEL away on 15th March 2016

Hello,

You can find the powerpoint for the lesson material in this folder:

Module 4 Resources

Look under alcohols and then L5 - esters and oxidation reactions

1. Complete the DNA and check your work
2. Make notes on the formation of esters from alcohols and carboxylic acids. Make sure you can name them too
3. Look up how to name an ether
4. Complete the question sheets set as homework - due next week (we'll check them in class). You need to collect the question sheets from the door of W8.

Work for Tuesday 1st March

As discussed yesterday I hope you have already spent some time completing the extension questions in your PAG folder.

Do make sure you return your folder to W9 before doing anything else!

I would now like you next to prepare for next week where we will carry out titrations.  In the resources folder is a powerpoint introduction, a guide to completing titration calculations and two question sheets with answers.

For next lesson please make notes on how to carry out a titration, complete the questions and mark them.  Bring all your work to our next lesson.

Thanks,
ERA

Please have a go at the past paper questions in the resources folder.  This is on top of the questions I asked you to complete for today.

In our lesson tomorrow I will check you have completed all the questions and you can ask me about anything you found difficult.

Thanks,
