Assignment-1: Separation of ingredients from the mixture of Table Salt and Sand
with practically. And answer the following
questions.
1. Which method(s) are used in the above
process?
2. Describe the working method serially.
3. Explain the observation and decision on
this experiment.
4. What kinds of precautions have you
taken doing this experiment?

1. The methods used for the separation were filtration and evaporation

Explanation:

The mixture of table salt and sand is first dissolved in distilled water. The salt is soluble in water but the sand is not. The solution is now filtered. The filtrate contains the salt solution while the residue is the sand. The filtrate is now evaporated to dryness to recover the table salt from solution.

From the experiment we can clearly see that table salt is highly soluble in water.

One precaution during the experiment is to ensure that the filter paper was placed correctly before filtration started.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
