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