The sea water can be classified as a homogeneous mixture as well as the heterogeneous mixture? comment

​

Answer 1

Answer :

Sea water is classified as a homogeneous mixture as well as heterogeneous mixture for the following reason :

• We know that sea water is mostly mixed with impurities, dead animals, plants,etc.

• Also, sea water is saline water.

• We can classify sea water with the above mixtures.

• In first case, if sea water is mixed with salt then it is homogeneous mixture.

• In second case if the sea water is mixed with solids liks dead animals, plants then it is heterogeneous mixture.

Heterogeneous Mixture :

• Heterogeneous mixture is a type of mixture which can be separated.

• In simple words, Heterogeneous mixture is a mixture where there is no uniform composition.

• Ex : Mixture of oil and water.

Homogeneous Mixture :

• Homogeneous mixture is a mixture which cannot be separated.

• In simple words, Homogeneous mixture is a mixture where there is uniform composition.

• Ex : salt and water.

Answer 2

$\bf\huge\boxed{Answers}$

HOMOGENEOUS-

✴ Salt of Sea water dissolves completely in water and dissociates in to sodium and chloride ions.

✴The salt solution is clear and transparent and salt cannot be separated from water by filtration.

✴Thus sea water is a homogeneous mixture.

HETEROGENOUS-

✴Sea water contains suspended impurities like decayed plants or animal material

✴Thus, it is called heterogeneous mixture.

Conclusion- Sea water are classified as Homogenius as well as Heterogenous.
