Question

A 25.00-mL sample of an unknown H2SO4 solution is titrated with a 0.1000 M KOH solution. The equivalence point is reached when 22.42 mL of KOH solution is added.
a) Write a balanced chemical reaction:
b) Identify the reaction as precipitation, acid-base, oxidation-reduction and/or gas forming.
c) What is the concentration of the unknown solution?

Explanation / Answer

a)H2SO4 + 2KOH --> 2H2O + K2SO4,,,,,,,,,, b)this is a acid + base --> salt + water ===acid base reaction,,,,,,,, c)moles of H2SO4 *2 = moles of KOH,,,,,,,,,,, 25*Molarity of H2SO4*2 = 22.42*0.1000,,,,,,, molarity = concentration =0.04484 M
