GCSE WJEC Chemistry

Which exam board are you using? If AQA or Edexcel just read the revision guide for science, they have everything required to know, it enough detail, not too much or not too less

Where would i find the revision guides? Also, not sure which one it is. I’ll have to check.

My chemistry teacher is new to my school and is definitely under 30. He can’t teach to save his life but I really need to know this stuff. Anyone got any chemistry knowledge they could share?

Currently we’ve ‘completed’ the topics;
•Substances and Chemical Reactions
•Metallic Bonding
•Ionic Bonding
•Covalent Bonding
•Simple Molecular Compounds
•Nanoscience
•Acids and Alkalis
•Neutralisation (we stared at acid dripping into alkali for an entire 30 minutes)
•Naming Salts (I understood this one)
•Balanced Symbol Equations (we did this topic last year so I understand this too)

Thanks guys xx

This site in the link is covering GCSE Science chemistry topics, including a number of the ones you mentioned.

I'm curious about your neutralisation lesson. You just sat there in silence watching the burette....?
What did the teacher talk about during that lesson?

on Amazon they have every revision guide known to man lol. Ask your teacher which exam board your year is using and then order the GCSE chemistry book for that exam board

Thanks 😁

Umm... he frequently mentioned ‘removing the funnel’ and he said somethhin about the universal indicator. He also mentioned that he’d broken two burettes during training.

Funny the bits you remember. I'm sure I have broken burettes too, but I tend to tell students about neutralisation if that is the topic

Some thoughts that may jog memories of what you should have discussed:
What do you understand by neutralisation?
Why would you use a burette?

You use a burette to correctly measure the amount of acid used to neutralise the alkali.
The only thing we wrote down in the lesson of a timportance was the title. The rest was a starter of naming salts.

OK. And why use an indicator?

I completed WJEC Chemistry this year and found that the revision notes made by Bangor Uni and the WJEC revision guide to be the most helpful for revision - they're definitely most targeted to the course and exam questions compared to CGP e.t.c

(I think the science syllabus has changed and the C2 and C3 revision guides are for the old spec and don't exist anymore but they still might be useful for the topics you're stuck on)

That would be the best revision guide to buy if you wanted to.

Hope this helps!

Thank you!!! This is going to be so helpful!

Adding an indicator to an acid or alkali will turn the colourless liquid red or purple. To work out when the alkali neutralises. If it starts off purple then you have to add acid until it turns green. The indicator will turn green when the alkali neutralises.

Np! And also, once in a while check the Bangor uni page as they might post the year 11 revision guide:https://www.bangor.ac.uk/ccm/gcserevision.php.en

They saved my life during exams so I would really recommend using them for all the sciences! (and its free)

Great. The moment of permanent colour change is the end point, the point of exact neutralisation.
So the titration enables you to know when the exact point of neutralisation occurs. This is useful if you want to find the concentration of the acid or alkali.

We never even needed to mention funnels

Thanks. Hopefully I’ll remember to check it. I’m super forgetful 😹😹

Haha don't worry I'm sure you will!

Are you in year 10 or 11 may I ask?

So maybe my teacher isn’t so bad after all. Thanks so much!!!

I remember writing a tiny bit about titration but it doesn’t appear to be in my book anymore.
