How to outline a method for separating chalk from potassium chloride
Answers
Hiii friend...
Chalk powder is insoluble. Hence, it can be seperated by sedimentation And decantation, also by filtration.
Answer:
Dissolve the mixture in water, filter it to obtain chalk powder and them evaporation to obtain potassium chloride.
Explanation:
As we know that potassium chloride is an ionic salt that is highly soluble in water and chalk is composed of calcium carbonate which is insoluble in water and precipitates when added to it.
So, first of all, we should dissolve the mixture in water. The potassium chloride salt will get dissolved in water and the chalk powder will settle down.
Now, filter the solution and we obtain chalk powder as the residue and chalk powder is separated from the mixture. Further, the solution of potassium chloride so obtained will be evaporated to separate potassium chloride salt from the water.
Hence, the mixture of the potassium chloride and the chalk powder is separated.
