![]() Times, the hydrogen end, the oxygen end is partially negative. And this end is partially positive, we've seen this multiple But if you were to lookĪt what's happening at an atomic level, you would see that you At a macro level, itĪppears to be homogeneous. Throughout the salt water seem to be uniform. Properties, even in a lab, you would see that the properties ![]() Look at the salt water, or if you were to measure its And if you were to go to the ocean, and if you were to just Salt water has sodiumĬhloride dissolved in water. That comes to mind for me, but we'll see a lot of these in our journey throughĬhemistry is salt water. Homogeneous liquid mixture or a liquid solution, the one We will also deal with solidĪnd gas solutions as well. Now, as can imagine youĪlso have liquid solutions and in chemistry, these are the ones that Now at a micro level, you can, because there are different But it is a homogeneous mixture of metals because at a macro level, you can't really see the differences. Going on in that metal, in that alloy, what's happening is you actually But if you were to look at it with a very sensitive microscope or based on the models that we now know what is And I should probably doīronze in a more bronze color right over here. If I have some type of metal alloy, if I were to just look at it like this, if I were to look at say bronze, well, from my point of view, it has the same properties Where at the macro level it's color, how well does it conduct electricity? How malleable is it? How hard is it? It looks like the properties are uniform throughout the alloy. Solid solution would be, say a metal alloy. ![]() Think liquid immediately, but it can be solid liquid or gas. We talk about mixtures, we could be talking about There's another term for it, which you have probably heard. View, it looks consistent any point of the mixture. That when you look at it from a macro point of There's heterogeneous mixtures, the opposite would be Mixtures are different, depending on what part of To see these clumps and depending where you are in the milk, you can actually see it with your eye, that you don't haveĬonsistent concentrations of the different substances. Of is chocolate milk that's not well mixed. Of the different things that have been mixed up. Parts of the mixtures have different concentrations Here at the extreme form is where with my naked eye, I could see that different Is referring to mixtures that if you look at itįrom a macro point of view, I'll do a heterogeneous liquid mixture. To see that prefix a lot, means different. Now there's fundamentally twoĭifferent types of mixtures. And it could be a solid,Ī liquid or a gas. If you take two or more substances and you were to mix them together, you are dealing with a mixture. It is the only metal we know of that is liquid at room temperature.You might already be familiar with the term mixture. Particles are free to move over each other, but are still attracted to each otherĪ familiar liquid is mercury metal.No definite shape (takes the shape of its container).Liquids have the following characteristics: However, because the particles can move about each other rather freely, a liquid has no definite shape and takes a shape dictated by its container. In a liquid, the particles are still in close contact, so liquids have a definite volume. If the particles of a substance have enough energy to partially overcome intermolecular interactions, then the particles can move about each other while remaining in contact.
