Multiple choice chemistry mix and separate dry methods of separation process of separating components of a mixture method of separation

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

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

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.

There is a mixture of X, Y and Z. If the mixture of X and Y can be separated by magnetic separation and the mixture of Y and Z can be separated by distillation.
The different states of X, Y and Z are respectively -

  1. Solid, solid, liquid.

  2. Solid, liquid, solid.

  3. All are liquids.

  4. All are solids.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Since X, Y can be separated by magnetic separation so X, Y are solids. 

Y, Z can be separated by distillation method therefore, Y, Z must be solid liquid mixture. 
Already we know Y is a solid hence, Z is a liquid.

Hence, option (A) is the correct answer.

In a mixture of X and Y, X can be separated from Y by magnetic separation.

Which of the following pairs will form X and Y?

  1. Sand, sawdust.

  2. Iron, sulphur.

  3. Iodine, sand.

  4. Gun powder and sawdust.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

X, Y are two solids making a mixture. 

One is component is magnetic, whereas, other is non-magnetic. 
Hence, the mixture must be of iron and sulphur.

Therefore, option (B) will be the correct answer.
