please help set up equation for Titration
« on: April 29, 2007, 07:24:26 PM »
I've been trying to figure out how to set up this problem if some one can help please tell me !!!!!!!!

In a titration experiment it was found that a 50.0ml sample of H2SO4 was neutralized by 62.50ml of 0.375m NAOH. What was the molarity of the H2SO4 sample?


I'm not shure if I use M=TT/RT to solveĀ  :'(

Always start with a balanced chemical reaction.

H2SO4 + 2NaOH --> Na2SO4 + 2H2O

no. of moles of H2SO4 : no. of moles of NaOH is 1:2
thus, molarity of H2SO4= 62.5 X 0.375 /(2 X 50) M.

Thanks..If you're satisfied, can gimme a scobbiesnack..hehe..

H2SO4 is "twobasic" acid. Its meam it can react with one or two molecules of NaOH.
You should know which of these reaction you did (which indicator you used or what pH is at the end of titration).
