Question

-+HOW CAN YOU SEPERATE CHALK POWDER FROM a mixture of sand toothpicks small pebbles sugar iron fillings

Answer 1

First use the fine seive to separate the larger particles like sand, toothpick, small pebbles and iron fillings.
Then use magnet to again remove the iron fillings if there were.
Then add water to the mixture and the sugar will dissolve but the chalk powder will settle down as it is quite insoluble.
Then take another very fine seive and pour the sugar solution to it and here the water and the chalk powder will be removed.

Answer 2

Answer:

If we have a mixture of chalk powder, sand, toothpicks, small pebbles, sugar and iron fillings, then following steps can be followed to separate chalk powder from mixture:

Step 1: Sieving -

It is a process used to separate large size particles from small size particles. Sand, toothpicks, small pebbles, and iron fillings are comparatively large size components as compared to chalk powder particles and sugar particles.

Thus with the help of sieving process we can separate sand, toothpicks, small pebbles, and iron fillings from the mixture.

Step 2: Magnetic separation -

With the help of magnet, remaining iron fillings particles can be removed from the mixture of chalk powder and sugar particles.

Step 3: Dissolution of mixture in water:

On adding the mixture to water, sugar will get dissolved while chalk particles being insoluble in water settles down at the bottom of the container.

Step 4: Filtration -

On filtration of mixture of water, sugar and chalk powder, chalk powder particles will left as residue on filter paper while mixture of sugar and water will be obtained as filtrate.

Thus by following the above steps we can separate chalk powder particles from a mixture of sand, toothpicks, small pebbles, sugar, and iron fillings.
