It is easy to separate cornstarch from water. They are in a "mixture" together. That means that there has been no chemical reaction. The cornstarch is still cornstarch; the water is still water. Therefore you can "physically" separate them using techniques like evaporation, filtration, distillation, etc. In this case, simple evaporation would work. Of course, you will not end up with a nice powder; rather you will end up with a very hard 'clump' of cornstarch. By the way: If you used tap water (which contains dissolved minerals), the minerals will also stay behind when the water evaporates. That will add to the clumping of the original corn starch and would mean that you no longer have pure cornstarch.

Fun with cornstarch:
Cornstarch and water is, indeed, a mixture ... but a very special one called a suspension (where the particles are suspended in the water and would settle out if given enough time). The cornstarch is not actually wet, even in water.!

This particular suspension has another special property, as it is a "Non-Newtonian" liquid. That means it acts like a liquid if you don't disturb it, but as soon as you do, it acts like a solid.

Example of what happens: If you stir the 'liquid' *slowly* with your finger, it acts just like a liquid. Try it again by stirring real fast and it will be like trying to stir a very thick kind of solid mass!

Search the Web for something like "cornstarch experiment" and you'll get lots of sites that will tell you how to do the experiment. And all it takes is cornstarch and water mixed to make a paste about like pancake batter!

How will you separate the cornstarch from water?

cornstarch does not completely dissolve in the water as it appears to do, so if you pour the mixture through a fine filter you should be left with the cornstarch trapped insid

How a mixture of sand and water can be separated?

By passing it through a filter, which traps the sand but allows the water to pass through.   That really depends on the circumstances; For instance if you are trying to re

How can be a mixture of mercury and water separated?

The decantation is very fast; water can be easily removed. Traces of water can be removed after filtering on an adequate paper filter.

What kind of mixture is cornstarch and water together?

Anyone who has ever watched a classic western movie knows about the dangers of quicksand. You know... that gooey stuff that grabs a hold of its victim and swallows them alive!

How do you separate the mixture of acetone and water?

The easiest way would probably be through simple distillation because the boiling points of acetone and water are more than 25 degrees Celsius apart with water being the highe

How would you separate an emulsion of cornstarch sawdust and water?

A paper filter should remove the sawdust (some cellulose may remain  in solution). Since cornstarch is a complex compound, the easiest  way to separate it is to boil (distil

How can you separate a mixture of salt and water?

In order to separate the mixture of salt and water you have to put  them both into a shallow container (lots of surface area) and let  the water evaporate. If you're interes

How do you separate a mixture of sand and water?

I would let the sand settle out of the mixture, then pour off the water, leaving the sand behind. If you needed to extract the remainder of the water, put the wet sand into a
