*** For those who have not noticed the previous comments about the accuracy in the video:
This video was made as a quick guide for one of my classes about what a titration is and it wasn’t meant to be an exact representation since that would have taken longer and I wanted to get to the end point faster so they could see what happens. I explained to them that it would need to be done more accurately if they were ever to do one themselves. ***

A titration experiment is used to calculate an unknown concentration of acid (or alkali) using a neutralisation reaction.
In this titration an alkali (with a known concentration) is carefully added to the acid (of unknown concentration) using a burette. The volume of alkali used in the experiment is needed in order to perform a calculation to work out the concentration of the acid.
The acid used in this titration is hydrochloric acid (HCl, 25ml volume, unknown concentration) and the alkali used is sodium hydroxide (NaOH, 0.1M concentration).

Useful equations to calculate the unknown concentration of acid:
number of moles = concentration x volume
concentration = number of moles รท volume
Concentration is measured in moles per litre (moldm-3)
Volume is measured in litres (decimetre cubed: dm3)
—–
The equation for this reaction is:
hydrochloric acid + sodium hydroxide —- sodium chloride + water
HCl + NaOH —- NaCl + H2O
(using subscript for the 2 in H2O)

5 Science Experiments To Do At Home
Totally wrong procedure you r suppose to take 10ml of oxalic acid in pippete not hcl and end point should be permanent pale pink colour not dark pink
It should be light pink in colour or we won't be able to get concurrent reading
Super
Awesome music .
thank a lot of you bro …………..it will be useful for me………
excellent very best
thank u so much for conceiving such a wise concept of titration.
He was getting frustrated lol
no offence great video
helped me for my ATP
so when they finished the experiment, was the resulting solution alkali not acidic as it was pink? I thought that it was supposed to be neutral but the indicator says its alkali… I'm even more confused than when I started
Thanks for Helping me tomorrow is my test
nice
Don't u think that the colour is too deep pink …very very very light pink depicts that titration is done. Dark pink is not accepted .
Splendid sir
the experiment helped me to understand,but the music was so fucking terrible
The bass!
thanks sir it had helped me at last moment
some salt analysis test is there sir.

Thanks
This experiment clarify more clearly that a lecture.
How can priper in to make naptelin and colour
Thanksalot
Thank you sir
