Titration Chemistry Problem: How to Calculate Volume and pH at Equivalence Point

[YoungStudent]

Sorry to disturb. I'm really bad at chemistry and i was hopping i could find some help...
My major doubt is about Titration for now and how to find what is asked even if i got the data needed.

Homework Statement

25.0 cm3 of 1.00 x 10-1 mol dm3 hypobromous acid ( HBrO ) solution is titrated with an aqueous solution of sodium hydroxide, NaOH(aq) with a concentration of 8.00 x10-2 mol dm-3

Homework Equations

Ka for hypobromous at 25º : 2.00 x 10-9
pKw of water at 25ºC : 14.0

The Attempt at a Solution

1-Calculate the volume of sodium hydroxide that must be added to reach the equivalent point?

2-Calculate the initial PH of the solution Hypobromous acid at 25º?

3- Calculate the PH at the equivalence point of the titration at 25º?



rather than the answers i would like someone to help me with which formulas i should use to solve it.

Thx in advance.

You have nicely used the template to dodge the first homework rule of the site - you have to show your attempts at solving the question to receive help.

Browse this site: http://www.titrations.info/ - it contains answers to all your questions (and more).

I did not asked for the answers i just don't have my template with the formulas, therefore i don't know which ones to use

But you were taught some equations used to calculate pH, weren't you? You were also taught something about stoichiometry, about reaction balancing - these are the building blocks that are required to solve the problem.

Chemistry is the only subject i really dislike in school but i have to do it, my media from 0-100 would be near 90 without chemistry, but it lowers it to 75.

Therefore i decided that i would not take it to the final exams, but the teacher decided that based on this type of exercises he will do a last test.

The exercise isn't even an homework, i found it in a school exercise book, but the method to solve it wasnt there and i haven't got no idea how to do it. I pass the exame and I am done with chemistry.
