Introduction:
In this question, Dhoni is trying to separate a mixture of sand, common salt, camphor, and iron filings. To do this, he adds water to the mixture in a test tube and shakes it well. By observing the results, Dhoni can determine which component dissolves in water.
Explanation:
When Dhoni adds water to the mixture and shakes it, one of the components dissolves in water. Let's analyze each component to determine which one it could be:
Sand:
Sand is mostly composed of small particles of minerals and rock fragments. It is insoluble in water, meaning it does not dissolve in it. Therefore, sand cannot be the component that dissolves in water.
Iron filings:
Iron filings are tiny pieces of iron. Like sand, iron filings are also insoluble in water. Hence, iron filings cannot be the component that dissolves in water.
Camphor:
Camphor is a white, waxy substance that is often used for its aromatic properties. It is sparingly soluble in water, meaning it dissolves only in small amounts. However, camphor does not completely dissolve in water. Therefore, camphor cannot be the component that dissolves in water.
Common salt:
Common salt, or sodium chloride (NaCl), is a compound that readily dissolves in water. When salt is added to water and stirred, it dissociates into sodium ions (Na+) and chloride ions (Cl-), which are surrounded by water molecules. These ions are then evenly distributed throughout the water, resulting in a solution. Hence, common salt is the component that dissolves in water.
Conclusion:
Based on the properties of the components in the mixture, it can be concluded that common salt is the component that dissolves in water. By adding water and observing which component dissolves, Dhoni can separate the mixture by filtration or other methods to obtain the remaining components.
