AQA Required Practical - Measuring the rate of reaction by disappearing cross (Sodium thiosulfate)

AQA Required Practical for GCSE combined science or chemistry. Investigate how changes in concentration affect the rates of reactions by both measuring the volume of a gas produced and monitoring a change in colour or turbidity.

Practicals are 15% of your exam grade, this could be the difference between a grade 4 and a grade 5 or the difference between grade 7 and grade 9. There isn’t a large amount of content but there are a lot of skills that can be tested, to help you with this I’ve made videos of all the practical and written a workbook full or exam style questions.

I want to help you achieve the grades you (and I) know you are capable of; these grades are the stepping stone to your future. Even if you don't want to study science or maths further, the grades you get now will open doors in the future.

Some of the links in here are affiliate links, where is get a small percentage of any money spent, if you like my channel and want to support my work, clicking these is an easy way to do it.

Disclaimer; You should not carry out any of these practical’s without carrying out a full risk assessment of your own first.

I am human, and I make mistakes, please point out any that you find and there is no need to follow that with a load of abuse.

Had my MATSEC Chemistry paper 2A today (Malta - advanced paper) did well :)

Can we also use solid sodium thiosulphate if there isn't it in liquid form ?

[uroojshahbaz]

Should I priorities my weakest subjects or the subjects I want to study at A levels?

Thank you! What a saviour this vidoe is!

"We can follow a rate of reaction by looking at it"
Yeah, no shit

Can you also tell us/ write in the description if it is c1 or c2? Thanks xx you're amazing
