Assuming the burette's graduation is up to 50cm³, 50.00 - 20.30 = 29.70 29.70 - 19.80 = 09.90 which we know is not enough to do another titration with since the other situations are ranging between 20 & 19cm³ and we only have 9.9cm³ of HCl left. So we need to add some more and take the new measurement, after adding more acid, as our initial brunette reading, THEN you can carry out the third titration without running short of acid😁
Great mum❤
Thank you for teaching me 😊😊
This is effective. Thank you. I hope you release the next video in this series and notify your subscribers😊
I like the way you teach 😊
I truely love this....
Supper presentation....
Good presentation
thank you cemastea education... for the grate explanations
Great*
nice explanation thankyou soo much
This is well presented
Thanks
THANKYOU🥳
Mmh after adding HCl for the third time why does the initial volume remains 10instead of 0.00??
When refilling the burette you don't have to start at the 0 mark always
Assuming the burette's graduation is up to 50cm³,
50.00 - 20.30 = 29.70
