Titration curves and indicators

Titrations - love them or hate them they are here to stay. This video looks at the 4 different acid - base titrations and how you can choose the right indicator for the right titration. Take a look it's easier than what you might think!

By the way I prepared for my As edexcel exams using your videos especially for Unit 1 Chemistry. And ended up with a high A of 269/300

[@angel127_]

mashallah

[@syedshayaan4004]

Could you do a video on sketching titration curves as its a very common question in edexcel a2

[@Masculinity-]

ohhh it makes sense now!!!!!!!!!!!!! thank you so much!

[@MohammadSalman-zq2rv]

Really Appreciate Your efforts sir.You have indeed explained in a simple and clear way

[@CristianoRaashid77]

You are wayyy better than Khan Academy!!!

[@quintonrenee2568]

Relax

[@chi20_]

Thank you so much . This has been very helpful.

[@AlleryChemistry]

Glad it was helpful!

How can a strong acid or bass act as a buffer? There’s no equilibrium I thought?

[@sajdahamad9980]

omg i finally get it thank youuuuu!

[@FunnyVideos-fq8tp]

why is there buffer action in the strong acid vs strong base curve? isnt a buffer made of a weak acid and its conjugate base?

[@nikhilraghavan3826]

Hi i keep confusing equivalence point and endpoint of a titration. Is the endpoint where the colour change occurs and the equivalence point where the moles of acid and base are equal in the titration?

[@physchemwithliz5879]

Yes 🙂

[@mattisprince7457]

G.O.A.T

[@saadpatel2734]

Is this in As 2015 course?

[@rowank445]

Thank you for this!

[@AlleryChemistry]

No problem!

[@danialjubouri]

Is the equivalence point the same as the end point? This is the main thing that’s confusing me :/

[@hammadisntreal]

end point is the point where the indicator changes colour. the equivalence point is when all of the acid or base gets neutralised and the reaction is complete.

How would the shapes of the pH curves change if you were to have varying concentrations of alkali added to acid? E.g. 0.5M NaOH added to 2M Ethanoic Acid

[@AlleryChemistry]

+Taras Mogetich This will just shift the position of the end point. In the example you gave you would need a lot of NaOH to neutralise 2M Ethanoic Acid. This would result in an end point further right than the equi molar concentrations as shown in the video. Hope this helps!

[@pyroflame5414]

I did an exam question and for Phenolphthalein a strong acid and weak base was incorrect as in it couldn't be used as an indicator. The acid was HCL and the base was ammonia, can you please provide assistance?

[@heeralchauhan1128]

Thank you!!!

[@AlleryChemistry]

You're welcome!

[@perfectosagie-ogbeide8334]

is equivalence point and end point the same thing?

[@theowilson7549]

yh

[@derivative8174]

can't you use Bromothymol Blue for all of them

[@ahsannadeem7231]

Really helpful thankyou ☺

[@AlleryChemistry]

You're welcome 😊

[@thegawjus22]

Do we have to learn the different types of indicators with their changes or will that be given to us in the exam?

[@AlleryChemistry]

Generally they give you them. I would try to remember important every day ones like phenolphthalein though.

[@pooyefidge7922]

thank you btc

[@aquienpuedaimportar3028]

Could you please explain why at some point the buffering suddenly stops working and the pH suddenly rises or falls sharply?

[@deuterium4.028]

The way u explain it makes it so simple thanku

[@AlleryChemistry]

Most welcome 😊

[@anilbajracharya5556]

love your videos but this is the worst camera angle lmao

[@derivative8174]

okay Anil

[@MohammadSalman-zq2rv]

So thanks a lot sir

[@suzyho2169]

From where the buffers come in titration

[@AlleryChemistry]

Buffers are created from a weak acid and it's salt. When you react a weak acid with a strong base you form a salt. You now have a buffer. Hope this helps.

[@suzyho2169]

Thank you so much . Your videos are awesome
