Answer 1

@aaronq

Answer 2

you gotta think about what these things are made out of. The easiest way to separate something is by using their polarities to your advantage.

fat, in general, is non polar. What about ice cream, what is ice cream made out of?

Answer 3

milk

Answer 4

what is milk made out of?

Answer 5

water, vitamins, minerals

Answer 6

and sugar (lactose). So are these ingredients polar or non polar?

Answer 7

water is polar right?

Answer 8

yes

Answer 9

sugar is also polar

Answer 10

so are vitamins and minerals (they're water soluble). So what you could do is shake the mixture and let it settle, the aqueous layer will separate from the oily (fat) layer. (depending on which is more dense, one will be on top of the other) After, you can just use a pipette (or syringe) to extract the top layer.

This won't work 100% because ice cream is a very complex mixture, itself. It milk, so it obviously has some milk fat and other non-polar ingredients. But it will get most out

Answer 11

You have to let the ice cream melt to do this

Answer 12

?

Answer 13

yeah, you could try to filter it if it's solid, but that won't really work. Milk fat is preddy dense and you'll get a combination of both in the filtrate anyways

Answer 14

Okay thank you so much for your help

Answer 15

no problem !
