Question

how we difference between sugar and chalk soluatio

Answer 1

take the mixture of sugar and chalk powder in a glass or stainless steel container. Add enough water to dissolve the sugar completely, and filter, using a cloth or filter paper. Sugar dissolves completely in water, whereas, chalk does not.

The sediment collected on the cloth/filter paper, is the wet chalk powder. Keep it in the sun to get dry chalk powder.

Heat the filtrate (Sugar solution) carefully to evaporate the water. You may stop heating when sugar crystals start to appear. Keep it in the sun to get dry sugar crystals.

Answer 2

Hey there !

1. If the sugar is in the form of crystals, you may sieve the mixture using appropriate sieve size. What remains in the sieve is sugar, what sieves through, is the chalk powder.

2. If the sugar too is in powder form, take the mixture of sugar and chalk powder in a glass or stainless steel container. Add enough water to dissolve the sugar completely, and filter, using a cloth or filter paper. Sugar dissolves completely in water, whereas, chalk does not.

The sediment collected on the cloth/filter paper, is the wet chalk powder. Keep it in the sun to get dry chalk powder.

Heat the filtrate (Sugar solution) carefully to evaporate the water. You may stop heating when sugar crystals start to appear. Keep it in the sun to get dry sugar crystals.
