Question

Your lab group has been given a mixture of sand and water. The task at hand is to separate the sand from the water, producing a container of sand and a second container of water. Maria suggests using the procedure called crystallization but several other group members think that filtration would be the best way to separate the two. Provide support for the second separation method, filtration. All BUT ONE point is valid.
A) Sand is an insoluble solid that does not dissolve in water.
B) The two parts of the mixture, sand and water, have different boiling points.
C) Sand particles are large enough to be stopped by a piece of filter paper, separating the sand from the water.
D) Although crystallization would separate the sand from the water, it would not provide a method to collect the water.

Answer 1

Answer:

The answer is B

Explanation:

I just took it on USATESTPREP

Answer 2

Answer:

B) The two parts of the mixture, sand and water, have different boiling points.

Explanation:

The two parts of the mixture, sand and water, have different boiling points. This physical property would help if using crystallization or distillation. It is not a factor in using filtration. Particle size is the key determinant in this case. Secondly, the task states that both parts of the mixture must be collected.
