Question

If a student pours a mixture of sand and salt water through a filter paper into a beaker, what will be found in the beaker after filtering?

Answer 1

answer: salt water

explanation: because salt water is a homogeneous mixture and cannot be separated through filter paper, the sand would be the only substance getting caught due to the fact that it’s a solid

Answer 2

We have to what will be observed if a mixture of sand and salt water is poured through filter paper.

In the beaker clear solution of salt will be there after filtering.

A mixture of sand and salt when added to water to prepare a solution, salt gets dissolved into water.

Salt dissolved in water as salt is easily soluble in water whereas sand is insoluble in water so it remains undissolved.

Now, the solution of mixture of sand and salt is poured through filter paper, then undissolved sand particles remain on filter paper. As salt solution is a true solution (size of solute particles very small), they can penetrate through filter paper.

So, in beaker only salt solution will be present after filtering the solution through filter paper.
