Title: precipitation reaction
Post by: ladyvoid on February 04, 2012, 03:41:00 PM

How would I balance Hg2Cl2(s) for a precipitation reaction? If you could run me through the steps that would be great.

OK, the first stem is to have a complete reaction.  So what did you start with, in the homework problem or laboratory.

That is all that I was given, along with "Use Na+ and NO3‾ as the spectator ions"

So you were given more.  ;)  OK, if you're supposed to leave out the spectator ions, what's left to be a reactant?

to tell you the truth, I'm not sure where to start. I just need to know the steps on how to solve this reaction... for some reason, I wasn't explained this properly.

the reaction would be something like this

chemicalA (aq) + chemicalB (aq) => chemicalC (aq) + chemicalD (solid)

In this thread, Hg2Cl2 was mentioned. Which one is it? A or B or C or D?
NaNO3 was also mentioned. Which one is it?
To be more precise, the NaNO3 is in solution so Na+ and NO3- was mentioned instead.
