Question

Loading is a process in which -

• A. Impurities become heavy and sink to the bottom
• B. Impurities float on the top
• C. Impurities vaporize
• D. None of these

Answer 1

The correct option is A

Impurities become heavy and sink to the bottom

Explantion for the correct Option:

Option(A): Impurities become heavy and sink to the bottom

• Loading is known as a process in which chemical substances like alum are added to the liquid to help the suspended particles of liquid to form sediment of solid.
• The suspended particles are lighter and do not settle at the bottom on their own hence, to make these suspended particles heavier and settle down, the loading process is used.
• Hence, Loading is a process used, in which heavy particles sink down at the bottom of the container, and water comes up.

Explantion for the incorrect Option:

Option(B): Impurities float on the top

• In the loading process, the Impurities are made to become heavier, so that they can be separated.
• We can not separate the floated impurities in the loading process.
• Hence, the given option does not coincide with the correct concept.

Option(C):Impurities vaporize

• The process of evaporation is basically used to separate the soluble impurities in a given mixture.
• Impurities vaporization does not undergo in the process of loading.
• Hence, the given option does not represent the correct concept.

Therefore, Loading is a process in which Impurities become heavy and sink to the bottom.
