A student added the following substances to water kept in four separate beakers. He stirred the mixture well and filtered each one of them through a filter paper. He would obtain a solid residue on the filter paper in the case of :
(1) egg albumin
(2) common salt
(3) chalk powder
(4) alum

Solution

Chalk powder (chemically known as calcium carbonate) is insoluble in water as it forms a precipitate in water and does not dissolve, so chalk powder will be obtained from filter paper.

Hence, the correct answer is option 3.

Q. Tony wanted to separate the mixture of dyes constituting a sample of ink in his chemistry laboratory. He marked a line by the ink on a filter paper and placed the filter paper in a glass containing water as shown in the figure. The filter paper was removed when the water moved near the top of the filter paper.
What would you expect to see on the strip, if the ink contains three different coloured components?
