 In this example we have copper nitric acid and copper carbonate. So a little hint to where we're going with this one. So what we want then is nitric acid so I can't remember the formula for nitric acid so I'll have my little table sitting in front of me so I can write them straight down. Once you memorize them you don't have to have that table anymore but it's really important if you can't remember the formulas to have them just sitting there while you're practicing, while you're learning so that you can become familiar and comfortable with each of these different formulas. So nitric acid HNO3 in solution with copper carbonate. Now carbonates are insoluble so I'm going to do this reaction and I'm probably going to do it with a solid copper carbonate. When with this reacts we're going to form water and carbon dioxide and in this case our salt is formed from the copper, the cation that's part of the carbonate and the nitrate. So copper from the formula I've made this a 2 plus it could be a 1 plus good if we actually have copper 2 just to remove some ambiguities there and then the formula for the nitrate will be CUNO32 and from NAGSAG all nitrates are soluble so that should be a soluble salt. When we're doing the net ionic equation we're not going to get quite the same thing this time because we've started with a solid, the solid we don't separate the ions however if this was a aqueous form then you would find that the ions that are here would also be cancelled out and we'd end up with the same overall equation. So just be careful because many of the carbonates are insoluble and therefore in order for these reactions to proceed you are often adding an acidic solution to a solid carbonate. Keep having practice and combine lots of these together in order to not only produce salts but also to name them. I gave you that as a little gift at the beginning of this slide. Copper nitrate specifically copper 2 nitrate because I've used the 2 plus form of the copper ion here is the name of this salt. Keep practicing and good luck and thanks for watching.
