If a 0.20 M acid with a smaller Ka than benzoic were titrated with the same NaOH, how would the equivalence point pH and volume compare to the equivalence point pH and volume of benzoic acid? Your answer for reach should be greater than, less than or equal.
Equivalence point pH:Equivalence point volume:
How many moles of bicarbonate ions, aluminum ions, and oxygen atoms are present in 26.0 g aluminum bicarbonate?
Yet the stock bottle clearly reads 0.0020 M. Why? Similarly, why is the initial concentration of iron (III) ion 0.10 M when the stock bottle contained 0.20 M iron (III) nitrate?
Why does the nitrogen atom of NH2 (and not the nitrogen atom of the NH) group of phenyl hydrazine act as the nucleophilic site in the format ion of the phenylhydrazones.
By looking at the structure of tetrabutylammonium bromide, explain how this reagent can carry ions from the aqueous phase into the organic phase.
magnetite was found to contain 2.5698 g of iron and 0.9816 g oxygen. What is the empirical formula for this oxide of iron?
