What is the reaction? NaOH + H2SO4 -> H20 + NaS04
« on: January 25, 2006, 04:10:24 PM »
Hi everyone,
Actually im finished with this class. I just have one last report to hand in. Its a simple acid-base titration. Its NaOH reacting with H2SO4. To finish it i would need a few questions answered.

What is the mol ratio between the acid and base?

What is the reaction? NaOH + H2SO4 -> H20 + NaS04 or something, cant get it balanced. With the other acid-base reactions i have no problem but this one always screwed me.

In a theoretical perspective why is it best to use a certain indicator?(In this case fenolftalein)

I hope you can understand my english and feel like giving me a little help :)

NaS04

Try with Na2SO4. No such thing as NaSO4.

This link will help you greatly. It'll balance your equation and it also gives you the molecular weights and proportions. I hope you'll be able to understand the site.

Also keep in mind what Borek posted.

yes good thing i pass by this part
my classmates and i were dabating if HCl would really react with NaOH to form NaCl at relatively very high concentration and at infinite dilution??
his reasons that they wont react is because they are both strong acid and bases(at high cocnentration) while my other classmate said it would react to form a salt of a strong acid and a strong base me on the other hand is an empirical person and just said i will have to go to the lab....
but i think the NaOH will act differently in infinte dilution than in high concentration,,,or is my hypothesis wrong????

No, i think the reaction between NaOH and HCl is the most easiest reaction, and it will happen in the same way on every concentrations of NaOH

why does the neutralisation of H2SO4 with NaOH release twice the energy than if HCl is neatralised with NaOH
