Title: net ionic equations
Post by: brandnewrocks13 on October 02, 2008, 12:33:04 PM

I've been trying to figure out these equations, but have been struggling a bit.

Saturated Chlorine water, mixed with HCL and KI

BaCl2 with NH3 and NaH2PO4

Na2SO3 and saturated bromine water

my professor said that the last two equations are 3 sub steps, but I'm having a hard time figuring it all out.
any help, or a push in the right direction would be much appreciated.

The final products are I₂, Ba₃(PO₄)₂ and Na₂SO₄.

thank you, that really helps a lot.  the only one that i'm still having problems with is the last one, i'm not sure how you got Na2SO4
can you maybe explain a bit?

Na₂SO₃ is a reductor, Br₂ is an oxidizer
