You mix the whole lot in water, this means that the saline Potassium Sulphate dissolves into the water. Filter off the Potassium sulphate solution and all you have left is the water. Evaporate off the water and you should be able to see the remaining crystals of Potassium Sulphate on the bottom

∙ 14y agoTo do the evaporation technique you first have to put the salt solution into an evaporating dish and place on a gauze, then place that on a tripod above a source of heat (like a Bunsen burner) and put it onto a high heat (if its the Bunsen burner your using put it onto a roaring flame). And now just wait. it should start bubbling and spitting now, when it does that just turn the heat source off, and wait for it to close.
However if your were doing this in school, you would probably use Grit. Therefore there would be more things to do before the evaporation process. First you would need to crush the grit in a pestle and mortar. once this is done you will need to dissolve it into some water. you will notice that there are some insoluble bits in the solution. So we now need to get rid of these. Filter the solution using filter paper and a funnel. Now follow the evaporation technique.

What would you do to obtain pure dry sugar crystals from a sugar solution?
Evaporate the water.
Can you obtain pure calcium nitrate crystals by evaporating the solutions to dryness?
no
What solution is most likely to produce crystals if it's disturbed?
Supersaturated
How crystals be obtained from a hot concentrated solution of a salt?
by cooling and then filtering
Why does alum make big crystals?
It's not that only alum makes big crystals.. There are so many compounds that can make big crystals. Even Sodium Hydroxide makes very good and big crystals. For crystals you need a uniform arrangement of atoms in space. For big crystals all you need is patience. The slower is the crystallization process the bigger crystals are formed. What industries do is called seeding. They make a good concentrated solution of the compound whose crystals are needed and then they put a crystal of the same compound in the solution. The new crystals form and attach to the crystal making quick and big crystals.
What would you do to obtain pure dry sugar crystals from a sugar solution?
Evaporate the water.
How can you make pure crystals of alum from impure alum?
To make pure crystals of alum from impure alum, start by dissolving the impure alum in warm water. Filter the solution to remove any impurities, and then cool the filtered solution slowly. As the solution cools, pure alum crystals will start to form. Carefully collect the crystals and allow them to dry to obtain pure crystals of alum.
What type of solution will form crystals?
a saturated solution will form crystals
What can you get from evaporating copper sulphate?
Evaporating a copper sulphate solution you can obtain anhydrous crystals of CuSO4. Increasing the temperature CuSO4 will be thermally dissociated.
How do you obtain big crystals of blue vitriol from its solutions?
Crystals in general are formed when solutions try to maintain concentrations at or below saturation. For example, a saturated sugar solution forms crystals when water from the solution evaporates and leaves excess sugar behind. Since supersaturation is a highly unstable and thus undesirable state of being for a solution, the dissolved sugar left behind will clump together at sites of nucleation to let the remaining solution remain below supersaturation. Crystals will continue to grow as long as the concentration of solutes in the solution can increase above saturation. To grow large blue vitriol crystals, one can simply prepare a saturated solution in a large container and let it sit undisturbed for as long as possible while evaporating steadily, removing the crystals when they are a satisfactory size or before the solution dries up entirely.
How would you obtain pure crystals of the salt?
You can obtain smaller and purer crystals by means of using precipitation or using the bigger crystals, because it is better to get them big, then cool them to make them small.
How will you obtain pure copper sulphate crystal?
boil off the solvent (usually water) until you are left with copper sulfate crystals. For getting back the copper sulphate crystals from copper sulphate solution, we have to first make super saturated solution by boiling, then allow to cool down & dried these crystals with filter paper.
What type of solution is most likely to form crystals as it cools?
A supersaturated solution is most likely to form crystals as it cools.
How would you get back salt from a mixture of sand and salt?
Add water and stirr: salt is soluble, sand not. Filter the solution. On the filter re- main sand, in the solution salt. After repetitive evaporations you can obtain salt as crystals.
What is the difference between iodine crystals and iodine solution?
Iodine crystal is solid Iodine. Iodine solution is when Iodine crystals are dissolved in water.
Why the collected crystals in a recrystallization are washed with cold water rather than warm water?
Warm water would make your crystals go into solution again
How do you salt out a solution?
Evaporating the water from the solution sodium chloride remain as crystals.
