Question

The steps involved in purifying impure salt crystals obtained from sea water are given below. But they are jumbled up. What is the correct order?

1: Filtration to remove insoluble impurities.

2: Crystallisation

3: Crushing

4: Boiling

5: Dissolving in water

A. 1 - 3 - 5 - 4 - 2

B. 5 - 2 - 3 - 4 - 1

C. 3 - 5 - 4 - 1 - 2

D. 3 - 5 - 1 - 4 - 2

Please give explanation as well...​

Answer 1

Answer:

Dissolving in water because sea water is soluble

Answer 2

Answer:

D - 3 - 5 - 1 - 4 - 2

Explanation:

The impure salt crystals are first crushed and then dissolved in water and then filtered to remove all the insoluble impurities and obtain a filtered salt solution.

This solution is further boiled to remove soluble impurities.

The water is left to evaporate and thus, pure salt crystals are left behind.
