When the question says the solution is made up to 250cm cubed is it done using sulfuric acid or by using water?🤔 And also would the moles of iron 2 sulphate be the same as moles of iron
For the acidified dichromate question, I found the mass of FeSO4 by multiplying the moles by 151.9 then taking the mass away from 7.49g and finding the moles of H20 by using this mass and dividing it by 18 then by the moles again and I got the same answer. Would this still be credited??
Excellent video, makes all these calculations so simple!
Great to hear!
Can you please do more of these?
Like the examples and practicals of redox titrations. They’re so difficult.
Thank you so much!
I guess it's pretty randomly asking but does anybody know a good place to watch newly released tv shows online?
@Ameer Brennan Try Flixzone. You can find it on google =)
@Theodore Coen yea, I have been watching on Flixzone for months myself :D
@Theodore Coen thanks, I went there and it seems like they got a lot of movies there :) Appreciate it!!
@Ameer Brennan Glad I could help :D
Why do we use distilled water instead of sulphuric acid to dissolve the FeSO4 in the second titration whilst we use it for the first titration?
insanely gooooood
Love this!

Usually made up with both
Moles of FeSO4 = moles of Fe
For the acidified dichromate question, I found the mass of FeSO4 by multiplying the moles by 151.9 then taking the mass away from 7.49g and finding the moles of H20 by using this mass and dividing it by 18 then by the moles again and I got the same answer. Would this still be credited??
Mary Sounds fine to me!
A very educative video
Could you tell me what the full equation of KMno + Iron stuff would be?
Thank you!
Has thiosulfate come up previously or do you think manganate will be more likely :) ?
Hitesh Anand Thiosulfate was tested last year so thinking non thiosulfate this year.
@@MaChemGuy ah okay thank you!!!
Why is it 130/18 and not 130-18?
Many thanks
Do we need to know the method
Ahmad Ghaffar Afraid so. See my teaching videos about it
MaChemGuy I can’t seem to find any playlist on module 5 redox
