How much salt should i add?

Question

2 questions:

how much salt canyou add to water (at room temp) before it is saturated [[1 quart of water]]???

&&

what happens when you boil that water and then cool it down?

Answer 1

see http://www.saskschools.ca/curr_content/c...

the solubility of salt (NaCl) increases with temperature, so room temperature water becomes saturated at 37g of salt per 100g of water (look at the NaCl line on the graph shown on the link above.  The graph looks very confusing as there are lost of lines for lots of different chemicals, you just want NaCl or salt)

when you boil it the water would dissolve more salt, and if you boil it for too long water will be driven off as steam and the solution will become saturated again.

as you cool it the solution will become saturated, and would possible become over saturated so that solid crystal appear out of the solution, especially if you have boiled water off as steam

you'll have to convert quarts to ml

( 1 quart [US, liquid] = 946.3 milliliter & 1 ml of water approximately equals 1 gram)

Answer 2

I think you have to add 1 tea spoon of salt.

Answer 3

I don't know

Answer 4

Say, you add equal amount of salt compared to the water. Then stir, to completely dissolve the salt. The solution is now saturated.

After utterly dissolving the salt in the water, boil the water until some evaporation takes place. The solution will now become supersaturated; since, the solute is now greater than the water. Salt doesn't melt nor evaporate, remember? A supersaturated solution is a solution wherein the the solute is greater than the solvent.

Answer 5

Saturation becomes higher at higher temps.  Without the exact temperature there is no way to answer this question.

Salt will dissolve faster in warm water than in cold. Less salt will dissolve in colder water. If you just about reach the saturation point for salt in water at a given temperature and then lower the temperature of the water, the excess salt will then precipitate or "un-dissolve" and appear at the bottom of the container.

There is a very good chart showing the amount of salt added to a gallon of water for each of the temps starting at 32 Deg. F.
