A level chemistry help

Hello, I am new to a level chemistry as I have only just began sixth form. The exam board is the OCR Chemistry A (post 2015 as the spec has changed). I am looking for potential A/A* resources that I can revise with daily and get the best possible marks at the end of my 2 years.

Please suggest anything that can be of help to me. Thanks!

Chemguide is a really good website, as is the Khan Academy. There's also a really great youtuber called E.Rintoul who makes good video's on chemistry

You could also watch (besides the ones already recommended) Tyler De Witt's videos on YouTube- he is seriously really good

If you're doing ocr spec AI'm sure you would have been given a thick textbook containing content for AS - that is so good just work through it no matter what order you're being taught if you haven't been given it but are doing ocr I can send you a pic?
Also there is a chemistry site which is called doc brown I haven't yet used it for a level but used it a Little at GCSE and it was quite helpful
Also u could use the chemistry teacher on YouTube (has a Funny d.p of a muppet doctor if you can't find it!)

Chemrevise, Chemguide, CGP book and some other websites that I cannot remember. I am recommended Chemrevise, CGP book and do a lot of past papers (including the old spec) and extra questions that are relevant to your syllabus! By the way my exam board is Edexcel but that is how I prepared for my Chemistry A Level and I got good grade. :smile:

Just buy the new spec CGP ones. If you need help with calculations I would highly recommend 'Calculations in A-level Chemistry' by Jim Clark as it covers content in most major exam boards

Hi I do OCR A and have started yr 12 this year too...
I use:
The OCR A textbook
CGP books
Notes from chemrevise
Then I do all the prcatice questions in the textbook and the CGP books
I also do some past paper questions
Primrose kitten science videos (discovered her just before my GCSE exams and she is really good! :smile:

)

Got D/Es at the beginning of the year. Used this method to revise and now I am working at a B/A grade! :biggrin:

Hi, I'm stuck on this chem practical question and was wondering if anyone could help. I've included my ideas so far in bold...
Salicylic acid can be used to make aspirin. Before using a sample of salicylic acid to make aspirin, a student purified the acid by recrystallisation. The method for recrystallisation is outline below:
Step 1 - The sample is dissolved in a minimum volume of hot water.
Step 2 - The solution is filtered hot.
Step 3 - The filtrate is cooled in ice to form crystals.
Step 4 - The crystals are collected by filtration, washed with cold water and left to dry.
Explain the purpose of each underlined point:
minimum volume and hot water -
Min volume of water as too much can mean crystals don't form, hot to dissolve the mixture.
filtered hot -
To stop the dissolved compounds recrystallising during filtration.
cooled in ice -
??
washed with cold water -
So the product/aspirin doesn't dissolve again and to wash away any soluble impurities.

Minimum volume of hot water - to form a saturated solution, so less product is lost in a solution.
Hot water - to disssolved all the soluble compounds.
Filtered hot - to removed insoluble impurities.
Cooled ice - allow the product to crystallise
Wash with cold water - to removed soluble impurities
