What is the molar concentration of a solution of sulfuric acid, H2SO4, if 8.09 mL react completely with 0.606 g of NaOH which was dissolved in 200 mL of water?
Solutions
Expert Solution
2NaOH + H2SO4 ----------------> Na2So4 + 2H2O
no of moles of NaOH = W/G.M.Wt
= 0.606/40 = 0.0152 moles
2 moles of NaOH react with 1 moles of H2SO4
0.0152 moles of NaOH react with = 1*0.0152/2 = 0.0076 moles of H2So4
molarity of H2SO4 = no of moles /volume in L
= 0.0076/0.00809 = 0.94 M
total volume of solution = 8.09+200 = 208.09ml
molarity of H2So4 in total volume of solution = 0.0076/0.20809 = 0.0365M

Sulfuric acid, H2SO4, is somewhat unique in that it is a
diprotic acid but it is also a strong acid. Thefirst dissociation
of H2SO4 is as a strong acid, and is thus a complete dissociation.
However, thesecond dissociation of H2SO4 is as a weak acid. Unlike
with other polyprotic acids, you cannotneglect the second
dissociation of H2SO4 because it will impact the pH of the
solution.

A chemist needs to determine the concentration of a sulfuric acid solution by titration with a standard sodium hydroxide solution. He has a 0.1157 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 14.02 mL of the standard solution. What...
