What happens when stuff dissolves I mean like what happens to the atoms and molecules then make it up I want to talk about two things here that you dissolve all the time salt and sugar these two things look very similar they're both like what kind of white powder is made up of little grains and you can pour both them into water and stir around and you see the grains get smaller and smaller and maybe break apart until eventually they've totally disappeared they've completely dissolved in the water that's what you see with the naked eye but if you had atomic vision and you can see the atoms that make up salt and sugar what would it look like as these grains broke apart and became invisible that's what we're going to talk about here so it actually depends whether something is an ionic or a covalent compound it depends on what it would look like when it dissolves so over here we have salt and this is an ionic compound this is what a grain of salt would look like and it's made of sodium ions na+ which are metals and Cl chloride ions these blue things here which are nonmetals so salt is an ionic compound made of metals and nonmetals sugar on the other hand is a covalent compound because it's made of nonmetals carbon oxygen and hydrogen and these nonmetal atoms are connected together into a molecule so a grain of sugar would look like this it would be a bunch of these sugar molecules all kind of lumped together notice that a grain of sugar is a lot more messy it's not nearly as well organized as an ionic compound this grain of salt over here anyway let's look at what would happen when we dissolve these we'll take a grain of salt dip it in the water and start stirring around with our atomic vision we're going to see that the atom that makeup this salt are going to come apart from each other they're going to break apart and they're all going to start floating around in the water individually this is what it looks like when salt dissolves okay now let's take our sugar here's our grain of sugar it goes to the water we stir it around and the grain of sugars going to break up like we saw the grain of salt break up but it's going to break up in a different way it's going to break up into the individual molecules that made it up but these molecules are not going to break up into the individual atoms they're going to stay as molecules and those molecules are going to start floating around in the water a big mistake that people make I don't want you to make this mistake is they think that when sugar or other covalent compounds dissolve they think that the atoms that make up the molecules totally break apart and then you end up with a glass of water that has all these carbon and oxygen and hydrogen atoms just floating around that does not happen big red X instead the molecules stay together well the atoms in the molecule stay together so this is a big difference between how covalent compounds dissolve where the molecules stay molecules and how ionic compounds dissolve where the grains of these things like salt actually break apart into the individual atoms so to answer the question what does it look like when something dissolves in water the short answer is it actually really depends whether you're talking about an ionic compound or a covalent compound if it's an ionic compound it's going to break apart into all of the individual atoms but if it's a covalent compound the clump of the molecules will break apart into individual molecules once it dissolves but the molecules themselves will not break apart into atoms they will stay as molecules dissolved in the water
