help i tried to figure this but i can't... for homework how do figure out if a glass of water has salt in it?

Question

without tasting it!!!!!!!!

Answer 1

boil it, then condense the water. If there is salt the salt will be left in the glass and the water will turn to vaper

Answer 2

You can do that by first boiling it and when its finished boiling then all that there will be left is the salt, if it really does have salt or you can also try to put an ice in it to see if it makes a weird appearence when the ice is in the glass with water and salt.

Answer 3

Pour a small 4 oz. glass of water, let it sit overnight, then check it in the morning. If there is any salt, it should gather around the edge of the glass and some of the water will evaporate.

Answer 4

Measure its density using a hydrometer. If there is salt in it it will be higher than 1.

If you need to be sure it is salt and not some other solute, dip a clean metal point into it and then put the point in a bunsen burner flame - salt will make the flame turn orange.

Answer 5

Let the water evaporate and see if you have salt in the glass.

Answer 6

Bake it. If there are crystals left over then it was salt water

Answer 7

try to freeze it salt water does not freeze at 32 degrees farenheight
