Glad you actually went over the equation in the end, if only all lab videos were like this.

accuracy was lost when a drop spilled onto the base of the retort stand while you raised the flask to the camera

You passed the endpoint, it's supposed to be a pink that's barely there.

ProudCroatian I agree he went too fast. You are supposed to add drop by drop. Only one drop will change the color.

thank you so much! i actually have a lab and our teacher showed us a demo but i couldn't understand at all but this really helped.

Same xd

when near endpoint, you must drop slowly, only one drop, you can turn on the van very quickly to get one drop from buret into erlene

Water does not affect the number of moles, just dilutes it

This was posted 9 years ago but thanks it finally helped me understand my assignment :')

You missed the end point

great help. thanks!

Is it okay if I accidentally added a drop of the indicator to my basic solution?

how do you calculate the molarity and concentration of the vinegar "taking into account the dilution factor" i.e. in this titration it is 1:4, correct?

is it neccessary to use water?can i do this experiment without using water and dissolving vinegar only ?

Why do you dilute the vinegar?

Thank you

Always take pilot reading and be patient .

Is the Phenolphthalein 1%?

Thank u

The endpoint was supposed to be faint pink

is it a 50ml burette ?

Thank you sir 💕💕💕💕💕💕💕💕💕💕💕

Pink colour of solution is very dark..i think due to this the accuracy of the solution is destroy.....

Pink too dark!

+Lambton Chemistry You added too much NaOH.

please i need trekt the work

You overshoot ...and there are drops where falling aside of the flask. This is not a experiment.

The pink color is too dark!

It's supposed to be pale pink... That's too strong

nope that was done wrong fam

molarity of 5% vinegar should be 0.83M not 0.87M!

Light pink

Dude you messed up

I think the solution is supposed to be light pink not dark pink right???

Yupp, it's dark pink because he passed the endpoint

the equation is wrong i think it is not balanced.....the oxygen atoms are uneven...........acetate is C2H3O2- you made a small mistake.

+kevin ram CH3COOH + NaOH -------> Na+ + CH3COO- + HOH You count the (OH-) or hydroxy group as one species. He did it correctly.

this guy just contaminated all that distilled water...

يعني طلاب الرافدين

can we do this experiment with 0.5 M NaOH?

+Peninnah Mathew Yes, just in the equation, replace the .1M with .5M

woohoo southpaw!

but thanks tho.........

Do you need to dilute the vinegar?

No necessary but he took 5 ml which was barely filling the flask , water was added to just increase the volume and it has not effect on titration.

That's definetely not the endpoint as you completely missed it.

0.89 molality gives 5 percent vinegar.what molality should i get to make 4 percent vinegar? i am a vinegar manufacturer.

Clear is not a colour.

I am a retired analytical chemist. If you follow the lab techniques as shown in this video, you will fail the titration lab.

There is no point in saying that without explaining why he would fail it and how can he avoid it.
