A 25.00 mL sample of a 0.5250 M H2SO4 solution is titrated with a NaOH solution using phenolphthalein as the indicator. It is found that 22.07 mL of the NaOH solution is needed to reach the endpoint of the titration. What is the molarity of the NaOH solution?

i think it's 102.9gm/Li , :\

Thank you! If you don't mind me asking, how did you arrive at that answer? :/

anonymous · Answer

from the equation 
H2SO4 + 2NaOH ---> NaSO4 + 2H2O
one mol of sulphric acid will react with two moles of NaOH
so 0.525 mole of H2SO4 will react with .... mole of NaOH
and then U can get the answer ,i think :)

sorry for being late :)
