Why Hydrated copper sulfate crystals cannot be obtained from a solution by direct heating?

Heating the saturated solution of Copper sulfate will not form the hydrated copper sulfate crystals because only after cooling down the saturated solution of copper sulfate then only the crystals of the hydrated copper sulfate can be formed

What are the factors that favor the formation of barium sulphate crystals?
temperature of heating and time for cooling of the crystals
What is the colour of copper sulphate crystals before and after heating?
Copper Sulphate crystals before heating r blue....but after heating I dunno , may be u should try and ask your Sci.Miss/Sir I'll get back when I get the other answer .
How do you separate the mixture of crystals of iodine and charcoal?
By heating it at low temperatures.
What type of precipitation forms from ice crystals?
Ice crystals don't precipitate. Precipitation of crystals happens when you create a supersaturated solution, and you do THAT by heating a solvent, adding enough solute to make a saturated solution at that temperature, filtering out the undissolved solute, and letting the solution cool. Ice crystals form.
Heating Hydrated Copper Sulphate?
On heating hydrated Copper Sulphate (CuSO4 . 5 H2O), the result is the removal of water molecules of crystallization, which for this very compound is 5 molecules per molecule of copper sulphate. The process cited above is termed as dehydration.
What do you observe when copper sulphate crystals are heated?
With sufficient heating, the blue colored hydrated copper sulfate crystals common at standard temperature and pressure will lose their water of hydration and lose their blue color. With further heating, the anhydrous crystals will melt.
How can anhydrous salt changes into their hydrated salt?
On heating, hydrated salts lose their water of crystallization and as a result, the crystals lose their shape and colour and change to a powdery substance.
What is anhydrous crystals?
A anhydrous crystal is one that has had all of the water molecules removed from it, usually by heating the hydrated crystal to a constant mass.
Can sugar be obtained from a sugar solution by heating the sugar solution and evaporating the water explain?
Yes - the sugar doesn't evaporate.
When a saturated solution is heated can it recrystallize more crystals?
Not while it is hotter, but if the heating results in any evaporation of the solvent, then yes, it will.
When crystals of feso4 are strongly heated the residue obtained is?
The residue obtained from heating crystals of FeSO4 (iron(II) sulfate) is Fe2O3 (iron(III) oxide) and SO2 (sulfur dioxide) gases. This is because the heating process causes the iron(II) sulfate to decompose, releasing water vapor, sulfur dioxide gas, and leaving iron(III) oxide as a solid residue.
How do you remove colour from copper sulphate using anhydrous?
The hydrated copper sulfate (blue color) become white after heating and releasing of water; the white anhydrous copper sulfate is obtained.
Anhydrous alumnium cloride cannot be obtained by heating crystals of AlCl3.6H2O why?
AlCl3 is covalent and hence when the water of crystallisation is evaporated, the AlCl3 will react with the water to form the hydroxide
How do you change the amount of water in a hydrated salt?
By heating this hydrate.
How do you separate sand iodine and sodium chloride?
Iodine can be extracted with ethanol.Sand is not soluble in water and can be separated by filtration from the water mixture.Sodium chloride remain in solution; heating the solution crystalline salt is obtained.
Oxygen can be obtained by heating?
With the exception of nuclear fusion oxygen cannot be obtained by heating anything. Certainly no heating process on earth is capable of producing oxygen.
Is heating hydrated sodium carbonate powder chemical or physical change?
Dehydration of hydrated salts is usually considered to be a physical change.
