A 38.74*mL volume of 0.50*mol*L^-1 sodium hydroxide solution reaches a stoichiometric endpoint with 19.37xx10^-3*mol of sulfuric acid dissolve in 50.0*mL of solution. What is the concentration with respect to "sulfuric acid"?
1 Answer
The first step (AS ALWAYS) is to write a stoichiometric equation......and I think your friend is right.
Explanation:
This is an acid base reaction, and as you know sulfuric acid is diprotic. And this is probably the source of the confusion: do I divide by 2; or do I multiply? We have all made these sorts of mistakes.
Given the stoichiometric equation, there were
And thus
Note that normally we would titrate a volume of
