2Hg is incorrect, Hg already gives off 2 electrons. 2Hg would mean that Cl becomes 4Cl, unless that's what your teacher wants. Not only that, but Hg has a positive charge, not a negative one. If it did, it wouldn't be able to pair up with either nitrate or chloride.

I think you're missing something from your initial equation. The equation you wrote doesn't match what Yusuke asked for.

Yusuke said:
Write net ionic equation to show the reaction of aqueous Hg2(NO3)2 with aqueous sodium chloride to form solid Hg2Cl2 and aqueous sodium nitrate.

He says that there are originally 2 Hg's on both sides.


So what he asked for is:

Hg[SUB]2[/SUB](NO[SUB]3[/SUB])[SUB]2[/SUB] [SUB](aq)[/SUB] + 2 NaCl [SUB](aq)[/SUB] → Hg[SUB]2[/SUB]Cl[SUB]2[/SUB] [SUB](s)[/SUB] + 2 NaNO[SUB]3[/SUB] [SUB](aq)[/SUB]

I'm almost certain that's a mistake, I interpreted the 2 as the 2 electrons Hg gives up. Hg2(NO3)2 doesn't make sense, because nitrate has a charge of -1. Hg having a subscript of 2 in this equation would mean that nitrate has a charge of -2, which isn't the case. Mercury(Hg) and nitrate together is an ionic bond, metal and non-metal, and the charges switch places and becomes subscripts. Mercury's +2 charge becomes the subscript 2 for nitrate, and nitrate's -1 charge becomes the subscript 1 for Hg, hence Hg(NO3)2. I'm almost certain Hg2(NO3)2 doesn't exist. If there were 2 Hgs, it wouldn't be written as Hg2, but 2Hg.

Thank you and I think so. I dunno, I guess it's because I tend to write small since I'm nearsighted.

Do you wear glasses?
I tend to get odd compliments, like "you write like a girl" or "your handwriting is very pretty" lol wtf

I don't actually. I really need glasses though. I tend to hunch while I write.

I've gotten a bunch of compliments on my handwriting. And then I find my old AP Psych notes and cringe xD

Hahaha, Yeah man, get glasses or else your vision might get worse.

Hopefully, that'll be soon. I've already had three episodes of where my eyes erupting into agonizing pain for hours because of the strain they got put on them throughout the day. I'm telling you, it's not fun. Can't even nap it off.

Silly people. Narutobase is a last resort. I've already used Google and gone to the exact same website(s) you guys are suggesting/copying and pasting from. It is, for whatever reason, not correct. Derps.

Try youtube next time.

The chemical equation is as follows:

Hg(NO3)2 + 2NaCl=HgCl2 + 2NaNO3

To find net ionic, you first need complete ionic, which is just breaking apart each individual molecule. It is as follows:

Hg2+ + 2NO3- + 2Na+ + 2Cl-=HgCl2(s0 + 2Na+ + 2NO3-.

In the complete ionic, you break down everything but the precipitate. To find the precipitate, you can just follow these rules, called the solubility rules


When writing a complete ionic equation, the precipitate, which is the solid that forms, remains together. The net ionic equation is just the two parts that form the precipitate and the precipitate itself:

Hg2+ + 2Cl-=HgCl2(s)

The bolded is your answer. If you have any questions about this post, ask away.

protip: silver/mercuric chloride are almost always the precipitates in a reaction they're a part of, their chlorides give away white precipitates almost instantly

also, on topic: Hg[sup]2+[/sup] + 2Cl[sup]-[/sup] -------> HgCl[sub]2[/sub]

Also, Nitrates are never a precipitate.
