Answer:

Step-by-step explanation:

. It asked to draw the hydration shells that form around a potassium ion and a chloride ion. When potassium chloride dissolves in water, label the positive negative and part partial charges on the atom. So the first thing is, don't be threatened by the term hydration shell. It's a lot easier then it may sound so. That's just asking. How do water molecules interact with your substances? And we've got potassium chloride assault and each of the ions are going to be charged. And so from the charge of the potassium and from the charge on the chlorine, you can easily guess how the the polar water molecule is going tio interact with the ions. So let's just go ahead and draw our potassium and our chloride. So remember, potassium is goingto have a positive charge. Thie chlorine is goingto have a negative charge. You remember that in a water molecule, the oxygen has a slightly stronger affinity for electrons than do hydrogen sze. So when the oxygen pools in the electrons a little bit stronger, it's goingto have a slightly negative charge on the hydrogen. Are each going to have a slightly positive charge. So when you've got your shell around your potassium, you're going tohave mostly the negative side. So you're going to have a little bit of a negative charge here. A little bit of positive charges on your hydrogen Sze so you can either put it right here is the positive partial positive. Or you can put maybe plus half on each of these hydrogen sze and then you're gonna have another number of your oxygen's. Because, remember, opposites attract. So if you have a positive charge here, you're gonna have more negatively charged molecules trying to interact with that. You're gonna have the the positively charged hydrogen tze a little bit away from it and then for the chlorine you're going tohave the opposite. You're going tohave the hydrogen. Is that air facing more towards Ah, the Corinne because again they're slightly positive. Ah, the oxygen slightly negative. And then you might want to just label that the's are partial charges and these are full charges. That's it
