Question

Volumetric

Answer 1

Hey WELCOME TO OPEN STUDY !!!!!!

What's your question ?

Answer 2

How I can solve a volumetric analysis?

Answer 3

Calculate the molarity of 25.0 mL of a monoprotic acid if it took 45.5 ml of .25 M KOH to neutrralized the acid?

Answer 4

\[Molarity = \frac{ molesof the acid }{ total volume of the solution }\]

Answer 5

Monoprotic acids are the ones tat give out 1 proton/ 1 H^+ that is an acid like HCl
So 1st write the balanced equation for this reaction
HCl + KOH ----> KCl + H2O
As u can see the reaction between HCl and KOH is 1:1
Now we have to find the moles of KOH
concentration = moles divided by volume
moles = volume * concentration
As we can see the no. of moles of KOH = no. of moles HCl
Now u know the moles of HCl
The total volume the solution = volume of HCl + volume of KOH
Now substitute these values to the mentioned equation !

Answer 6

Thanks a lot. You should be my teacher. He never wrote this on board he just used power point.
