Video 4: - Elemental sodium has a configuration of 11 electrons and an inner core of two with an almost outer core of eight with one extra electron on the outside. - The chlorine ion has 17 electrons, again, a similar arrangement with two and eight. But it has seven electrons on the outer core on the outer shell.
What is important for stability for each is one to gain an electron and the other to lose an electron. Elemental sodium will participate quickly with elemental chlorine and transfer that electron very rapidly and with explosive tendencies to give an eight-electron outer shell. Each of these now has stable octets which is important. The sodium has lost an electron so it is now positive. The chlorine has gained an electron so it's now negative. sodium chloride-- overall, a salt just like we have been using for decades. These kinds of situations where you have sodium chloride, potassium chloride, potassium bromide, et cetera, these are salts. They will conduct electricity in a proper fashion. Summary of results: - The V8 has a considerable amount of sodium. - Soy sauce, just one tablespoon and it lit up very quickly. - There is a little bit of sodium in vinegar. It isn't very much, only five milligrams - We got more conduction with a lemon juice. While there is not likely to be too much sodium in there, its cited as zero, but there is potassium salts and other kinds of salts. enough in lemon juice to conduct a little more electricity than vinegar, but both extremely small. Whereas, for soy sauce and V8, it is considerable how much is in one of these 340 milliliter cans - about 650 milligrams of salt. That’s the one thing that all of the nutritional establishment guidelines indicate is to try to get rid of some of the salt in the diet could reduce saltshakers to have small holes. Video 5: If you take a look at Google Earth, we see a white spot on the western side of South America - western side of Bolivia - the Uyuni salt flats are a very substantial salt bed. People can bike on this. People tour here and come in cars, and buses etc. Salt is collected on a regular basis. Chile: Salt's on the road and there are communities there that deal with the salt in the same way that they do in Bolivia. The chunks are substantial that you can pull up – size of a loonie. Sell them in forms of llamas and other animals for tourists. Even possible to find a chameleon that takes on the coloration of that white dust that's all over the floors or the surface of the landscape. Of course, salt is dealt with on a massive scale in terms of what's in our food. Some people use it in a little cup taking pinches of salt, distributing it over the food in chunks, getting a little salt thrill from certain chunks that are there as opposed to the finely divided salt that we normally see.
