State a method to separate ammonium chloride from a mixture of ammonium chloride and potassium chloride.

  1. Sedimentation

  2. Sublimation

  3. Magnetic separation

  4. Solvent extraction

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Ammonium chloride sublimes on heating therefore it is easy to remove it by sublimation from a mixture of ammonium chloride and potassium chloride.

Iron and brass paper clips can be separated from each other by

  1. Magnetic separation

  2. Chromatography

  3. Centrifugation

  4. All of above

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Magnetism is a form of separating mixtures which involves using a magnet to attract another magnetic object away from the substance it is in. Iron gets attracted towards magnet and are separated from brass.

Magnetic separation is a process in which magnetically susceptible material is extracted from a mixture using a:

  1. Frictional force

  2. Gravitational force

  3. Both a and b

  4. Magnetic force

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Magnetic separation is a process in which magnetically susceptible material is extracted from a mixture using a magnetic force. This separation technique can be useful in mining iron as it is attracted to a magnet.

The various methods for separation of solid-solid mixture includes:

  1. fractional distillation

  2. leaching

  3. magnetic separation

  4. centrifuge

Reveal answer Fill a bubble to check yourself
B,C Correct answer
Explanation

Fractional distillation is used to separate two liquid mixture based on difference in their boiling point.

centifuge is used to  separate solid from liquid,
Leaching and magnetic separation can be used to separate solid- solid mixture.

Which technique could be used to obtain the elements X and Y from the compound $XY$?

  1. Filtration

  2. Distillation

  3. Electrolysis

  4. Crystallisation

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

To separate elements X and Y from the compound XY we have to break it into ions,

and the process of breaking compound into its ions are known as electrolysis.
