Hi I'm Kirstie! I'm a Chemistry teacher on Instagram (@chem.jungle) and RU-vid :)
I've been teaching Chemistry for 11 years and have worked in the UK, China and Singapore. I'm currently on a gap year and I'm going to be making videos, quizzes and resources to help you to learn to love Chemistry as much as I do :)
This channel is aimed for IGCSE or IB Chemistry students so please share with friends, students or anyone who needs more chemistry in their life.
Don'f forget you can also follow me on instagram @Chem.Jungle for more content!
What was in the 1st test tube before you put the Sodium Hydroxide in? Is there any way to precipiate or remove copper from NAOH solution? I need to purify a NaOH solution which has copper in it thank you,
at 34:45, shouldn't the number of moles of Al_2(SO_4)_3 be 0.600? I thought you divided by the coefficient just to find which one is limiting. Does it affect the number of moles?
