Question

Identify the processes and their correct sequence that can be used to obtain salt from a mixture of salt, sand, and water.​

• A. Evaporation $\to$ Filtration ​
• B. Filtration $\to$ Decantation ​
• C. Decantation ​$\to$ Filration
• D. Filtration $\to$ Evaporation ​

Answer 1

The correct option is D Filtration $\to$ Evaporation ​

To obtain salt from the given mixture, following steps will be performed:

1. Filtration: Large mud particles are separated first as they are insoluble in water. Salt is soluble in water and passes the filter paper.
2. Evaporation: Now, evaporation is performed to remove water from the salt-water mixture. Salt is left out in the container.​
