If one beaker contains sugar and water, while the other one contains salt and water, what can I do to test which one contains the salt or sugar, without tasting it? Can I let the water evaporate and be able to tell the difference between sugar and water? Or if you filter it, one gets filter while the other one doesn't get filtered?

It says that I'm not suppose to know by smelling nor tasting!

Set up an experiment....
you will have two knowns...one of salt..one of sugar....
set up to unknowns....
measure the specific gravity of each dissolved in distilled water using a common hydrometer...then compare the results with the knowns by inspection.

extremely trouble-free and dissimilar approaches. a million. basically style it. no matter if it is sugar water, it is going to likely be sweet to style. on the necessary aspect, between the approaches of figuring out elements is using all of your senses, style being one in each and every of them, so long because it isn't unsafe; it is actual for this reason. 2. trouble-free evaporation. you are able to evaporate a numbers of drops of the answer and basically enable it air dry or facilitate the evaporation utilising warmth. ultimately, you need to make certain sugar crystals. you are able to make certain the presence of minute crystals through utilising a low potential microscope. 3. Use of a densitometer. A sugar answer will be denser than basically organic water. the answer that reads off with a significantly better cost is the sugar answer. 4. etc. utilising different state-of-the-paintings instruments, besides the undeniable fact that the above concepts ought to suffice.

cook it tell water evaporates. smell should be different. you would be able to decipher what you are smelling is sugar or salt. i always though cooked sugar had a unique smell.

One way would be to test the solution for its ability to rotate polarized light. Sucrose rotates polarized light, salt does not.

you can boil the water to see if it dissolves and if it dissolves it salt and if it like get thick its sugar
