Hi, I'm Robin Higgins and this is simple examples for solubility. Alright so lets look at three different examples of something being soluble. First our simple table salt, sodium chloride. Now if we put salt into water and we mix it around, dissolve it, it will form a clear solution. Which means that it has successfully been soluble. Which means, remember homogeneous solution you can't tell that there's no chunks. There's no different parts of it. It's not bumpy or anything. It's completely the same everywhere. And at 20 degrees Celsius sodium chloride can fit 35.89 grams in every 100 grams of water. So this is how soluble salt is in water. Now lets look at something that has a little bit of properties, sugar. Or in this case specifically sucrose. So sucrose has a lot more solubility in water. For every 100 grams of water you can actually put in 202 grams of sucrose. So this is why we can get so much water into things like sodas and other drinks that we have. So it's a lot more soluble then salt. And so solubility we usually think of it as a solid going into a liquid. But that's not necessarily the case. So in our last example this is something we are all familiar with is carbon dioxide going into water. So this is what's in your soda. The bubbles, the fizz have actually been a gas dissolved into water. So these little bubbles are carbon dioxide and you can get them into water a little differently then how you get sugar or salt. For gas we actually put it under pressure so that's why if you pop a soda it makes a noise, it's the pressure being released. So this is our mixture with water and carbon dioxide bubbles. And then we pressurize it and even though you can't see inside of a soda if you did, it wouldn't have those bubbles. It would just be a liquid like this. And once you release it the bubbles come out, they're no longer soluble. And these are kind of three different examples. You have a little bit, a lot, and then a gas actually going into a liquid. I'm Robin Higgins and this has been simple examples of solubility.
