@@pradeep4791 a titrant is a substance of a KNOWN concentration. That means, the concentration is precalculated. Unfortunately, that was not explained in the video
I don't know how God brought me to your video, but I am so thankful for it. I was freaking out in fear of not knowing what to do in chemistry practical but this showed me everything I needed to know. THANK YOU SO MUCH!!😁😁
Shouldnt the unknown substance always in the burette? Because with indicators apart from phenolphthalein such as Methyl Orange and Thymol Blue it is way easier to see the color changes that indicate its endpoint if the tyrand(HCL) is placed on in the burette and the known is placed in the conical flask first?
Hi Ivan, this is Ravi from Pearson Education. Are you interested to work with us? I am looking for a person who can create lab experiment videos of chemistry and you are pretty good in that. Hoping to listen from you.
The burette and the pipette should have been washed. The burette first with de ionised water and then the solution going into the burette. Secondly, the pipette should have also been washed with the solution going inside of it and the conical flask too. Results wouldn’t be very reliable
im sorry but the unit of your final answer is incorrect. Remember, you are looking for the concentration of substanceA. the unit must be the same as the unit of your substance b (which is mol/L)
