Question

Biology Practical 4 observation table

Answer 1

Here is an experiment to understand crystallization clearly:

Step 1: Take 50 ml water in a beaker

Step 2: Add sugar in it and stir it

Step 3: Now heat the solution

Step 4: Repeat the process continuously

Step 5: After some time there will be a point at which no more sugar can be dissolved in water. This stage is the saturation point, and the solution is referred as a saturated solution

Step 6 : Now filter the sugar with the help of a filter paper

Step 7: Collect the filtrate in a glass bowl and cool it

Step 8: We will observe that some fine crystals are formed in the bowl

Step 9: The process of filtration can separate these crystals. The liquid left after the removal of crystals is known as mother liquor
