Question

The 'sea water' can be classified as a homogeneous mixture as well as a heterogeneous mixture. Comment.

Answer 1

i) Homogeneous mixture:-

• Seawater is the mixture of water, salts, and other many suspended impurities. Apart from these many gases are also dissolved in it. Because of the presence of a mixture of several dissolved gases in seawater, it is classified as a homogeneous mixture.

​Homogeneous mixture

• Uniform distribution of components.
• Components cannot be distinguished easily or by physical process.

• Components of homogeneous mixture cannot be seen through naked eye

ii) Heterogeneous mixture:-

• Due to the presence of salt and suspended impurities, seawater is also classified as a heterogeneous mixture.

Heterogeneous mixture

• Non-uniform distribution of components.
• Components can be distinguished easily or by physical process
• Components of heterogeneous mixtures can be seen through naked eyes
