Approximate Value of Equivalence Point? I am not too sure how to get this.
Approximate Molarity of Ba(OH)2(aq) solution? I can calculate this but because I'm not sure how to get the EP, I can't.
Please assist.
Show how you calculated the approximate molarity of Ba(OH)2(aq) solution? volume of Ba(OH)2(aq) solution dispensed Molarity of H2SO4(aq) solution used Total volume of H2So4(aq) Conductivity Dispensed (mL) S/cm So 2. S-20 13 D value of Equivalence Point _9. SomL Molarity of Ba(OH)2(aq) solution Show how you calculated the molarity of the Ba(OH)2(aq) solution:

Explanation / Answer

At equivalence point, the conductivity value is at its minimum, because at equivalence point the Ba2+ and SO42- ions are no longer present in free state but they combine to form the BaSO4 ppt.

From the data provided, the minimum conductivity value of 130 is obtained after addition of 5.6 mL of acid.

Now, assuming the conc. of Ba(OH)2 as 'x' M, we use the following equation to solve for x:
MacidVacid = MbaseVbase

0.1*5.6 = x*10

Thus,

x = 0.056 M
