Can anyone tell me from where I can practice questions relating to IR spectrometer?

Have you done the book/past paper questions first?Can anyone tell me from where I can practice questions relating to IR spectrometer?
It's a new addition to the AS syllabus, so no past papers yet. But I have done the book.Have you done the book/past paper questions first?
There are 2 iron atoms in Fe2(SO4). The reaction shown only involves 1 Iron (III) atom.View attachment 60400
why do we consider 0.2moldm^-3 due to Fe3+ ions
if it involves onle one Fe3+ then y do we mutiply the conc wid 2....SO42- = weak base ...it doesnt affect the pH...isnt tht so?There are 2 iron atoms in Fe2(SO4). The reaction shown only involves 1 Iron (III) atom.
I didnt really understand your question but from what i understand:if it involves onle one Fe3+ then y do we mutiply the conc wid 2....SO42- = weak base ...it doesnt affect the pH...isnt tht so?
If you find something please share them here. I'm also not very well prepared regarding IR spectroscopy.Can anyone tell me from where I can practice questions relating to IR spectrometer?
Someone told me that this topic can be practiced from the edexcel past papers. I'll share the questions here soon which I found. But if you like you can see the past papers on your own as well.If you find something please share them here. I'm also not very well prepared regarding IR spectroscopy.
May this help you, found on net.Someone told me that this topic can be practiced from the edexcel past papers. I'll share the questions here soon which I found. But if you like you can see the past papers on your own as well.
