We know that chlorine is a gas from the right side of the periodic table so that is an anion. Silver is also a metalĪnd is also a cation. And those are alwaysĬations when they're alone. And we know that it's positively charged because sodium is a metalįrom the left side of the periodic table. But how do we know which ions are cations and which are anions? Well, sodium is positivelyĬharged so it's a cation. Many many many times until we end up with the salt crystals that we dissolved in the water. Surrounded by four sodiums, and this pattern repeats Sodium chloride will have chloride ions on all four sides which in turn are Just like little bar magnets, they attract so cations only react with anions to form new compounds. Two kinds of ions right? Cations are positively charged, and anions are negatively charged. What just happened here is that both of the compounds are ionic. Immediately want to ask is, what is this white stuff down here? The key to understanding To the silver nitrate solution and there you see your precipitate. Add some drops of sodium chloride, also known as your salt water Salts found in limestone, we can use a very similarĪnd substantially more familiar ionic compound, table salt. Reactions that deposited silver and veins across our landscape.

And we can use it right here at this desk to recreate the ancient Silver nitrate, is similar to that ion-rich water that seeped through the Montana limestone

Out how to economically extract gold from sea water. That have driven themselves crazy trying to figure Might be nice to master some precipitation reactions. And that was not a stutter, a hundred million trillion. Value, the ocean contains about one hundred million There are also tons of other things dissolve in the ocean, including quite a lot of gold. What we call salt when not doing chemistry, is the most common salt. The water evaporates, leaving the salts behind in the ocean where over the eons, it has built up leaving the ocean super salty as we know it today. If these dissolvedĬompounds stay in solution until they get to the ocean, they pretty much stay there forever. Potassium and copper salts, and most notably, sodium salts are dissolved as water Salts and the solution, all kinds of stuff gold and You can't feel this, but it's extremely heavy because silver is a pretty heavy element. Insoluble silver compounds that fell out of solution. Where conditions were right, silver ions in the water reacting with ionic compounds or salts, in the limestone to make With ionic compounds ran through cracks and So the rich silver veins in Montana formed when water stuffed And this is purely my preference because that's how my teacher said it when I was being taught. When we talk about an ionic compound that's fallen out of solution, I say precipitate to distinguish it from precipitate which is more the verby sound. Yes, precipitate isīoth a noun and a verb. Reactions and solution, they fall out as a solid precipitate. But some ionic compounds can overcome even theĭissolving power of water. Those little polar molecules slide their way between the ions dissolving massive amounts A positively charged ionĪnd a negatively charged ion held together by their charges might form a crystal when they're dry but add a bit of water and Water, as we've discussed here before, is pretty dang good at dissolving stuff. And for us here, it allĬomes down to a little thing called solubility.

(upbeat music) Precipitation: it's stuffįalling out of other stuff. I can do it right here on this desk and all I need to get started is this. Of millions years ago, they're also the key to To how silver was deposited in these mountains hundreds Happen to be one of the best ways to produce chemicals Our waste water drinkable and they've been used byįolks for thousands of years to get rich, because precipitation reactions What create geological deposits in the earth as well as Took place over the eons called precipitation reactions. Specifically, it's hereīecause of countless chemical reactions that And of course, all that silver got hereīecause of chemistry. Silver was also a bigĭriver of the settlement in the western United Purity and warding off evil whether in the form of Shiny electrically conductive,Īnd oh so useful, silver has been valued since ancient times and has a reputation for Nitrate on that big boy and you'll be ready for Or perhaps you're in the bath one day and as you reach for the soap you notice a wart on your big toe. Fortunately, the cutlery is made of silver and you know how to use it.
