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
Why does copper sulphate solution not evaporate when heated?
When heated blue copper sulphate solution does evaporate!!!! The result is BLUE copper sulphate crystals of the penta-hydrate (CuSO4.5H2O). If you continue to heat these blue crystals, they will turn white in colour as you drive off the water of hydration. CuSO4.5H2O(s)(Blue) ==heat==> CuSO4(s)(white) + 5H2O(g) The analogy of hydration is like holding a ball in your hand. Your hand is the copper sulphate, and the ball is the water. Open your hand (heat) and the ball falls away(water is released). Your hand and the ball remain separate objects (NOT combined). Similarly the copper sulphate and the water remain separate molecules (NOT combined). It's just that the one is held (in the crystal lattice), by the other.,
What substance is given off when salt solution is heated gently?

What substance is given off when the salt solution is heated gently?
Water vapor is given off when a salt solution is heated gently. As the solution heats up, the water molecules begin to evaporate, leaving behind the salt particles.
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.
Which substance is left behind after you evaporate sugar solution?
Sugar is 'left over' because it is nonvolatile
How can salt or sugar be recovered from solution?
suppose there is a mixture of salt and water..salt completely dissolves in water so after a certain time we will not be able to see salt particles in water..to recover the salt from the solution we can evaporate water and salt residues will be left behind.
What is left of the solution?
The solvent evaporates from the solution leaving behind the solute
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.
What substance was collected by evaporation?
The substance collected by evaporation is typically the solvent that was initially dissolved in a solution. As the solution is heated and the solvent evaporates, it leaves behind the solute in a more concentrated form.
