NOTE: at 2:00 concentration calculation should say 0.01 / 0.025 = 0.4 mol/dm^3

In a frigging nutshell😂

[@mondirapaul]

Idk how you did it but FuseSchool, after a year of doing titrations and just having to copy other people’s answers and calculations, I have finally understood what a titration does and how to calculate such in just 5 minutes. That’s a feat of a great teacher.

[@fuseschool]

That's great! So glad to hear that 🙌

Thanks,, the visualised calculations are totally helpful

[@thecortex1535]

Why did you put 0.01 as the moles for the unknown solution? Are the moles of the known and unkown solution same?

[@fuseschool]

We have assumed that in the equation for the reaction, 1 mole of known reacts with 1 mole of unknown. But it could have been 2 to 1 etc.

[@sliceofficial6013]

How did you get the mole for the unknown at 1:58

[@fuseschool]

For the purposes of this calculation we are assuming that one mole of the known solution reacts with one mole of the unknown, so once you have calculated the number of moles of the known solution that have reacted, this will be the number of moles of unknown. If the two solutions react differently, say 1:2 or 2:3 (it will always be a simple ratio) then you have to include this fact too.

[@ZaidMGames]

at 2:00 is it just me or is the answer wrong for the concentration of the unknown substance. 0.01/0.025 is equal to 0.4 not 0.04

[@fuseschool]

It should be 0.4, you are right! Thanks for noticing!

[@daviddavies6461]

@@fuseschool thanks for replying.... I thought i missed something out too....I spent the last half hour trying to understand why everyone in the comments were saying it was so easy. It is easy, but concept is easy to understand here, but the final answer is 0.4.

You may have forgotten to mention that the first example assumes that you have a 1:1 ratio btw :)

[@randomusage767]

Too good👍🏻♥️

[@fuseschool]

Thanks a lot 😊

[@RayyanSaboor]

how do we know both of them have the same moles? like if we find the moles of know how do we know the unkown also has same mole?

[@javaidakhtar4544]

ye

[@BRAVE_N3W_W0RLD]

Thank you so god damn much

[@fuseschool]

Most welcome!

[@kirbytaylor4045]

Step 3 tells us to find the molarity of the unknown solution by dividing the moles of the known solution, by the volume of the unknown solution. How does this make sense?

[@cianle5996]

lol at the moment i am wondering that too ?

[@cianle5996]

maybe they assumed that they already know what exactly the substance is in the unknown solution (like in the 2nd example). Therefore, they can write the equation and know the moles ratio of the reactants. So maybe the reactants moles ratio is 1:1. But in the second example, the ratio of sodium hydroxide to sulfuric acid is 2:1 and they still plug the moles of NaOH to H2S04. which is incorrect i think.

[@fish-yn4zf]

rip to my homies using liters/mol

[@indhujareddy439]

You can directly give a formula instead of this much explanation (N-a×V-a)=(N-b×V-b) dilution law

[@newstube6861]

Like your videos

[@grumpyentity2029]

I completely understand the maths behind the answer to the last calculation, but the logic doesn't make sense: if substances neutralise they must have the exact same amount of stuff in total, and since the two substances had the exact same volume they must have had the exact same amount of stuff per amount of space in order to total the same number of moles, so how can a volume with a concentration of 0.3 mol/dm^3 neutralise with an identical volume that has a concentration of 0.6 mol/dm^3?

[@fuseschool]

You are nearly right, but remember that a di-basic acid, such as sulphuric acid, has two replaceable hydrogen atoms per molecule, but an alkali such as sodium hydroxide has only one -OH group per molecule. So you need two moles of NaOH to neutralise one mole of H2SO4. Check out the video at 4:00 again.

[@---ne9xp]

I’m still slightly confused on why the known solution has the same amount of moles than the unknown. That makes zero sense

[@C453YD]

That is what confused me also

[@Samuitsuki]

Sometimes the two solutions react one to one, and thus has the same amount of moles.

[@joelcarter9264]

What if the mole ratio is not 1:1??

[@hyunwoocho9176]

Isnt it 0.4 mol/dm3

[@melayuthailand1366]

[@lauramcsharry2442]

Is it just me or is their an error in the concentration calculation of the unknown substance. 0.01/0.025=0.4 not 0.04?

[@olafkowenicki4665]

nobody asked

[@wesa1998]

Were did they get the 0.01 from? They seem to have carried it over from the mole value for sodium hydroxide which if you are going to do you carry it over and divide by 2 to get the mole of sulphuric acid and go from there

[@fuseschool]

Yup, you are right, there's an error. Sorry about that!

[@ManojHari2011]

molarity is the molar concentration given by M/L so you might have to change units

[@christinaconnery9419]

this is just a fancy way of saying M1V1=M2V2

[@fuseschool]

Sort of... But you can only use M1V1 = M2V2 when the mole ratio is one to one... If the mole ratio isn't one to one, it's better to go through the long way to ensure you don't make any mistakes.
