Question

Describe how you could experimentally differentiate between the following pairs of solutions using a common aqueous solution:
a.) Pb(NO3)2 or KNO3
b.) HCl or H2SO4

anonymous · Answer

using a common aqueous solution?? are you allowed to use only one solution to add to these?

anonymous · Answer

Yes, but I believe you can use a different solution for a and b.

anonymous · Answer

potassium chromate for a.. PBNO3 gives yellow precipitate
barium chloride for b..  H2SO4 gives white precipitate

anonymous · Answer

How do you know which to use, though?

anonymous · Answer

Sorry, this is for a post-lab, and we're supposed to determine this by writing out equations; I have no access to chemicals to tell the different ppt colours.

anonymous · Answer

oh..

anonymous · Answer

I'm sorry... I'll use Potassium Chromate and Barium Chloride to write our equations and see if there's a difference between products?

anonymous · Answer

ok..

anonymous · Answer

Thank you so much, though! :)
I really do appreciate the help. :)
