Question

Aerated drinks are examples of a ______________ (gas-liquid/liquid-liquid mixture).

Answer 1

Mixtures

• The type of substances which contain two or more different components which are not chemically linked, are called mixtures.
• The components retain their individual property even when they are mixed.
• The components present in a mixture can be separated.
• There are two type of mixtures, homogeneous and heterogeneous mixtures.

Homogeneous mixtures

• The components present in a mixture are in same phase, where we can not distinguish the presence of components with our naked eye.
• Salt solution is an example of homogeneous mixture.

Heterogeneous mixtures

• The components present in the mixture are generally in different phase, we can distinguish the presence of components with our naked eye since they remain physically separate.
• Sand in water is a good example for heterogeneous mixture.

Aerated drinks are also a type of mixture where the gas is dissolved in the mixture, and we can say that it is a gas-liquid mixture since the layer of gas appeared to be separated, it is a heterogeneous mixture.

Hence, aerated drinks are examples of a gas-liquid mixture.
