Thanks

Why is purity 1g/0.847 and not the other way around

You have no idea how much this saved me. Thank you so much!

Thank you so much for the insight madam

Please step 7 is 0.847/1* 100

went through so many videos and was extremely confused on the topic, until I found this video. It's so beyond clear I cannot explain how useful it was. Thank you so so much.

I have a question regarding on redox titration experiment. Can you explain what is the purpose of standardisation on aknown concentration sodium thiosulphate solution?

What is the order of reaction

This is so well explained, thankyou so much !!

Step 7 is incorrect as the mass of KIO3 should be over mass of the impure KIO3

Great video sir!

Thank you so much for such a clear explanation. This video has been extremely helpful

This video was very helpful Thank you Mr Allen :)

Thanks so much....I can't expressed how I feel bcos being an empty headed student in this topic just changed to a sensible student by watching ur video

this is a great explanation, I just wish you wrote the actual rate formula down. Appreciate it tho, this was still very helpful

That’s so helpful, thank you :)

i love it....

Thanks ..

At 1:12, you still haven't explained why the hydroxide can't grab the central hydrogen.

Thanks so much dear this video hv helped alot

Thank you!!

Great video

youre sooo beautiful

Good explanation ❤

Thank you so much mrs lucas

Thanks, really helped glad I found this.

Thank you ma'am

Fantastic video!!

thank you 7 years later your video is still helping

I want you to know i loved this vid, saved me for my practical thank you SOOOO much

underrated... thankyou so much

These are very good and clear explanations.

thank you so much

Could you help me how to solve this problem ? Ma'am.... One vitamin C tablet is dissolved in an acidic solution. Add 2 g of solid KI and 50.00 mL of the 0.01795 M KIO3 solution. The solution is titrated with a 0.1258 M thiosulfate solution and reaches the endpoint at 6.12 mL of titrant. What are the moles of triiodide consumed by the vitamin C tablet?

OMG hey thanks this really helped me with redox reactions!!!!

Video was very useful but the mcvities bant is too dead

this was super helpful for me, thank you!!

Thank you

Thank you so much! My struggle has only been in deriving the first equation from the question.

you're an awesome teacher, thank you

I have a commercial Povidone-Iodine solution that I would like to test to know the amount of free iodine in this solution. how do I prepare the Iodate solution? should I jump to equation 2 right away and start titrating with sodium thiosulphate without the previous reaction?

Nice explanation!!

Am I meant to memorise the first equation you wrote ? Because it wasn’t written in the question and I’m not sure where you got it from

Thanks for such a amazing video . I wish I could have teachers like u in our university 😢 By the way it's amazing 👏

do we need to know sodium thiosulfate redox calculations for aqa? thanks

Thank u soo much❤ Finally I understand iodometric 😍❤ We want more practices to be able to calculate precisely

please make more video - especially electrode Potentials, nmr and practicals

Good video

Lifesaver. Thank you! What exam board do you use?
