Homework Answers
The reaction is
H2SO4 + 2 NaOH ----------------> Na2SO4 + 2H2o
The relation of molarities at equivalence is
V1M1/n1 = V2M2/n2 where N1 and N2 are the stoichiometric coefficients of H2So4 and NaOH respectively.
23.00mL x M /1 = 25.67mL x 1.760M/2
Thus Molarity of H2SO4 ,M1 = 0.982 M
Alternatively
meq of acid = meq of base
2x23.00mL x Molarity = 1 x 25.67 mL x 1.760 M
[as H2SO4 is dibasic and NaOH is monoacidic]

An unknown sample of sulfuric acid was determined by the method used in this experiment. The sodium hydroxide was standardized by titration of 0.0855g of oxalic acid dihydrate with 25.28mL of sodium hydroxide. 10.00ml of the unknown sulfuric acid was then titrated to endpoint with 32.34mL of the same sodium hydroxide solution. What was the concentration of the sulfuric acid? (Show your work!!)

A chemist needs to determine the concentration of a sulfuric acid solution by titration with a standard sodium hydroxide solution. He has a 0.1435 M standard sodium hydroxide solution. He takes a 25.00 mL sample of the original acid solution and dilutes it to 250.0 mL. Then, he takes a 10.00 mL sample of the dilute acid solution and titrates it with the standard solution. The endpoint was reached after the addition of 13.55 mL of the standard solution. What...
