What happens when you dissolve salt versus what happens when you dissolve sugar in water?
that’s what we’re gonna talk here!
you can put both of them in water and steer around and you’ll see the grain gets smaller and smaller and maybe break apart until eventually they totally disappear.
They’ve completely dissolved in water, that’s what you see with the naked eye.
■ But if you had atomic vision and you could see the atoms that make salt and sugar,,,
what would it look like as the grain broke apart and became invisible?!
>>> that’s what we gonna find-out here!
It actually depends, whether something is an ionic or covalent compound?
It depends on what it’d look like when it is dissolved in water.
● so over here we have a salt and this is an ionic compound👇
And this non metal atoms are held together into a molecule.
■Note that a grain of sugar is a lot more messy than an ionic compound(Grain of salt).
We are gonna break apart and they all gonna start floating around in the water individually.
This is what a salt looks like when it is dissolved (as mentioned in the above figure)
Now let’s take sugar
Here’s are grain of sugar it goes into the water and Steer around then it gonna break up, like we saw the grain of salt break up, but its gonna break up in a different way.
it’s gonna break up into individual molecules that make it up but these molecules ain’t gonna break up into the individual atoms.
They are gonna stay as molecule and the molecules are gonna start floating around in the water.
A big mistake that people make and I don’t want you to do this mistake🚫
They think when sugar or other covalent bonds dissolved, they think that the atoms that make up the molecules totally break apart and then when you end up a glass of water that has already all these Carbon, Oxygen and Hydrogen atom just floating around but that don’t happen:-
This is the big difference between how the covalent molecules dissolve where molecules stay molecules and how ionic compounds dissolve where the grain of salt actually break apart into the individual atoms.
So to answer the question what is it look like when something dissolved in water, the sured answer is it actually depends whether we are taking about an ionic compound or an covalent compound.
If it is a ionic compound its gonna break apart into all the individual atoms but if it’s a covalent compound then the joint molecule will break apart into the individual molecules once it dissolved.
