Reflections

If there is no crystallization , then we won't be able to obtain a soluble solid from a liquid in solid-liquid mixture .

Precautions taken

The solution is heated to ensure that Real World Application : Many modern calculators have a liquid crystal display (LCD). The liquid crystal is sandwiched between two thin pieces of glass in an LCD. The bottom material is a mirror, which reflects the light as it passes though the LCD. The outer material is a piece of conductive glass that changes the arrangement of the liquid crystals molecules beneath it, and stops light from reflecting back, creating the images you see displayed on the screen.

The steps/process

Step 1 - The impure solid is dissolved in a solvent .

Step 2 - The solution is heated to evaporate most of the solvent .

Step 3 - The hot solution is allowed to cool .

Step 4 - The cold solution is poured to obtain the crystals .

The product obtain

- a soluble solid .

Type of mixture involved

- Solid-liqid mixture .
