What ds is left behind when a solution is heated?
When a solution is heated, the solvent usually evaporates, leaving behind the solute in a more concentrated form. This process is known as evaporation or drying.
How could mokhtar purify the salt again?
The sand can be extracted by filtration and the salt solution left can be heated to evaporate the water and leave the salt behind
What is left of the solution?
The solvent evaporates from the solution leaving behind the solute
Where did the substance that appeared at the bottom of the evaporating dish after it was heated come from?
It is likely the substance was a salt such as sodium chloride or copper sulphate that was in solution. When the water evaporated it left the solid salts behind.
Which substance is left behind after you evaporate sugar solution?
Sugar is 'left over' because it is nonvolatile
What happens to the salt solution after evaporation?
the crystallized salt is left behind
Which of the following is a way that minerals are formed a. Minerals are left behind when super-heated water within the Earth cools. b. Minerals are left behind when water evaporates. c. Minerals are?
Several minerals are left behind when water evaporates.
Does it take longer to saturate a heated solution than a cold solution?
No, a heated solution will saturate faster.
When potassium permanganate is dissovled in water and heated what is the color of the disillate and original solution?
The original solution is an intense violet color because it contains dissolved potassium permanganate. The distillate is clear (colorless) because only the water distills and the potassium permanganate is left behind, as it is non-volatile.
How does evaporating separate soluble substances'?
The water is heated and vaporizes, but the substance dissolved in it can't evaporate and is left behind.
Why must you let a solution evaporate at room temperature in order to get a salt?
The solution does not have to be at room temperature. Depending on what the solution is, the solution must be heated to it's proper boiling point in order for it to evaporate. Everything has a melting, freezing and a boiling point, and the salt's melting and boiling point's are extremely high, therefore the salt will be left behind when the solution is evaporated, unless the solutions boiling point is higher then the salt's boiling point.
How can you separate the water and salt?
Salt and water can be separated by heating the salt solution. The solution is heated till the water turns into steam. When entire water steams out, the white particles left behind is known as salt. This is the first step in obtaining salt from sea water. There water is collected in large areas and the water is allowed to evaporate. After the water evaporates the salt left behind is impure. So further processes are done on that impure salt to make it pure.
