Question

Discuss the seperation method of salt and sand by using suitable substane

Answer 1

Physical Separation of Salt and Sand

Since both salt and sand are solids, you could get a magnifying glass and tweezers and eventually pick out particles of salt and sand.

Separating Salt and Sand Using Solubility

One method of separating salt and sand is based on solubility. If a substance is soluble it means it dissolves in a solvent. Salt (sodium chloride or NaCl) is an ionic compound that is soluble in water. Sand (mostly silicon dioxide) is not.

Separating Mixture Components Using Melting Point

Another method to separate components of a mixture is based on melting point. The melting point of salt is 1474°F (801°C), while that of sand is 3110°F (1710°C). Salt becomes molten at a lower temperature than sand. To separate the components, a mixture of salt and sand is heated above 801°C, yet below 1710°C. The molten salt may be poured off, leaving the sand. Usually this in not the most practical method of separation because both temperatures are very high. While the collected salt would be pure, some liquid salt would contaminate the sand, like trying to separate sand from water by pouring off water.

Answer 2

Answer:

Solvent extraction method

Explanation:

first we have to try to dissolve the mixture in any solvent such as water and after tjat we have to do sedimentation and deccantation so our sand will get seperated and after that by doing distillation our salt and water will get seperated
