What separation technique is used to produce rock candy from a sugar solution?

Answer 1

Yes.

Answer 2

Yes.

Answer 3

crystallisation is a separation technique

that uses evaporation to separate the

parts of a solution (mixture). The solvent (liquid)

evaporates and leaves behind the

solute (solid) as crystals.

Answer 4

Crystallization makes rock candy.

The sugar solution must be super-saturated, meaning that as much sugar as possible has been dissolved into the liquid. Heating the liquid increases the amount of sugar that can be dissolved. Once the super-saturated liquid cools, some of the sugar must crystallize out of solution. If you place a string or a stick into the liquid, the sugar crystallizes onto the surface, making rock candy.

I tried this as a kid a few times by heating up sugar water in the microwave, adding more sugar to dissolve, reheating, until no more sugar would dissolve. I was never patient enough to let the crystals grow completely, which would take many days. You shouldn't disturb the crystals as they are growing.
