What types of mixtures are represented by the following:
(a) Carbon dioxide gas dissolved in water.
(b) Air containing suspended particles.
(c) Soap bubbles are formed by blowing air into the soap solution.
What types of mixtures are represented by the following:

(b) Air containing suspended particles.
(c) Soap bubbles are formed by blowing air into the soap solution.
(a) When carbon dioxide gas is dissolved in water homogeneous mixture is formed. Carbon dioxide and water in forming the mixture depict the uniform composition throughout the mixture. The particle size of the solute in the mixture is microscopically tiny which cannot be separated easily by any of the physical methods.
(b) Air-containing suspended particles are a heterogeneous mixture. In heterogeneous mixture distinct phases of the layer can be easily visible. Solute particles are big enough in size and are easily visible through the naked eye. In the air also dust particles suspended are easily visible.
(c) Soap bubbles form by blowing air into the soap solution is a heterogeneous mixture. In a bubble, we can see a thin film of water in the form of a bubble and air trapped inside the bubble due to which it is floating.
