Practice Problem: Titration Calculations

[@muhammadaminkhan2249]

Yes we can V1...known volume C1...unknown conc. V2...known volume C2 ..known conc. V1c1= v2 c2 50×c1=35.2×0.250 C1= 0.177

[@whatisknown2569]

Thanks man! But I think there is easier method We can use M1V1=M2V2 and we don't have to convert mL to L because it cancels each other in the process, and you will get the same answer 0.250M x 35.23mL the whole divided by 50mL and you will get 0.17615 to be precise

[@padhle_chinmay]

Great method to solve quickly, thanks man!

This works on monoprotic acids, or reactions that are 1 to 1 mole. It gets janky once you move into diprotic or triprotics.

[@whatisknown2569]

@@mattmao47 Maybe, but glad u told us, thanks

[@geetee12345]

I was thinking the same thing, Wow what a roundabout way to do it where Titration Formula works just fine. This is a GREAT reminder of the mole relationship in all this, I would use this in an Honors class, IMO ...and it does factor in if you have a diprotic acid like sulfuric ;)

Thank you so much! I had to learn titration myself today and I was so confused!

nice exercise again! one small thing, the information given shows 35.23 mL NaOH at first but when calculating this changes to 35.24 mL NaOH. No big deal tho, the answer doesn't change cuz of it :P

[@Bettymg.1]

I caught that too

[@seasound1400]

Hello professor can u help me to solve that:if 38 ml of 2M H3PO3 is used to titrate 150ml of NaOH what is the molarity of the acid?

[@TheDaphinator]

Literally saved me tonight. Thank you so much!

[@odio_stationofficial3420]

Same bro, 1 year after you, I also got saved the last night🌙 before practical exam..😅😅

[@giftsadique1806]

Sir can you please do reaction Mechanism of Organic chemistry and how do we convert carboxylic acids to esters...when we are doing reaction Mechanism between Ethanoic acid +NaOH as an example so that NaOH doesn't act as a base.

[@ProfessorDaveExplains]

fischer esterification

[@lanomusambazi8654]

Thank you for the well explained clip.

[@notnormal7565]

Damn! His students must love him!

[@isabelazapatapalacio5250]

can we use M1V1=M2V2 to solve this?

[@Js12135]

yes M1V1=M2V2 works and is arguably more straight forward than the method he explained but I guess its a case of personal preference which one you use

[@ShivamGupta-zv5ly]

[@Nuclear.chain.reaction]

is it true that mol acid will equal mol base even if one is strong and the other is weak?

May you please help me with the balance chemical equation between potassium dichromate and oxalis acid. Thank you

[@maganonashilongo]

I mean oxalic acid not oxalis 😢

[@saidergashev8268]

You can also just multiply 0.25 by 35.24 and dividing it all by 50 giving you the same answer. I forgot what it was called but skips unit conversion.

[@steppingintostem]

The formula for dilution yes. M1V1=M2V2

i need to calculate percentage error for the titration of KHP vs NaOH howvere i dont know the theoretical value !!! someone help me out here professor dave

I’m confused on where you got 0.0500 l at the end

The question says 50ml so he converted it into litres = 0.05L

Hi professor....

[@worthlesschild4052]

Personally I understood nothing whether it be from my chemistry teacher my classmates or KZbin

[@AnjaliReddy-qy1ep]

not the elevator music-

[@johnsubba7288]

Just a comment..You made that very simple calculation a complicated one...since both units are same(ml not mass) we can easily use M1V1=M2V2 equation. I try to make chemistry as simple as possible for my students..this will confuse them.

[@ProfessorDaveExplains]

This is not a dilution, this is a titration.

[@johnsubba7288]

I am sorry, but it is same for the titration...The units converted to liters and further...Unless there is difference in the number of molecules reacting on the reactant's side..since it is A+B - C+D reaction the M1V1=M2V2 will work..But if the reaction are like 2A+B ---- A+2B - product..then the different method is used similar to yours...M1V1/M2V2=2/1 .. considering 2 the moles reactant of A and M1V1 for A. The same for B... Well there are 2-3 ways to come to the same conclusion..I just commented on making it easy...But I admit that you make great videos...👍👍✌️

[@JemilaJNunes]

@@johnsubba7288 You are absolutely right, I teach my students this method as well. When the moles of reactant are not equal (as in the example you showed), you can use the following modified equation: NBCAVA = NACBVB where NA and NB are the stoichiometric coefficients of the acid and base respectively that appear in the BALANCED chemical reaction. CA is concentration of acid, VA is volume of acid. Using this formula, you never have to guess about the mole ratios, and bonus, you don't have to convert mL to L.

[@johnsubba7288]

@@JemilaJNunes exactly my point..you hit the bull's eye on what I was trying to say..Thanks, Jemila.

[@caitlingee642]

maybe he was trying to show how to do other problems that don't have a 1 to 1 mole ratio?
