  1. a homogeneous solid in liquid mixture

  2. a heterogeneous liquid in liquid mixture

  3. a homogeneous liquid in liquid mixture

  4. none of these

Show answer
Correct Option: C
Explanation:
Vinegar is homogenous solution because it is a completely uniform solution of liquid in liquid type of mixture (acetic acid in water)

The heterogeneous mixture of soot particles in air is a mixture of:

  1. solid-in-solid

  2. solid-in-gas

  3. gas-in-solid

  4. gas-in-gas

Show answer
Correct Option: B

Unlike gases, can all liquids in liquid mixtures form solutions.

chemistry separation of substances substances and mixtures formation of mixtures and types of mixtures based on states types of mixtures

  1. True

  2. False

Show answer
Correct Option: B
Explanation:

No, not all liquids in liquids mixture form solutions

we know that "like dissolve like", so, the liquids which have same polarity only form solutions.
for example: water and oil have different polarity and hence they do not form solution.

Match the column I with column II and select the correct option from the codes given :

  1. P-(iii), Q-(iv), R-(v), S-(i), T-(ii)

  2. P- (v), Q- (iii), R- (iv), S- (ii), T-(i)

  3. P-(ii), Q-(i), R-(iv), S- (v), T- (iii)

  4. P-( iv), Q- (iii), R- (v), S-(ii), T-(i)

Show answer
Correct Option: D
Explanation:
Chalk-water mixture- A heterogeneous solid-liquid mixture

Glucose solution- A homogeneous solid-liquid mixture

Fizzy drink- A gas-liquid mixture

Smoke - A solid-gas mixture

Air - A gaseous mixture

Hence the correct option is D.

Which pair is a miscible liquid mixture?

  1. Ethylalcohol and water

  2. Mercury and alcohol

  3. Benzene and water

  4. Carbondisulphide and water

Show answer
Correct Option: A
Explanation:
Water is polar and has hydrogen bonding. Since, ethyl alcohol has oxygen atom it also undergoes hydrogen bonding when mixed with water. Also, ethyl alcohol is polar due to high electro-negativity of $O$, due to which it mixes with water. Hence, ethyl alcohol and water are a pair of miscible liquid mixture.
