Concept explainers
Seawater is composed of salt, sand, and water. Is seawatera heterogeneous or homogeneous mixture? Explain.
Interpretation:
The type of mixture for sea water should be determined.
Concept introduction:
The mixture can be defined as a physically combined material made up of two or more different substances. The mixture can be of two types, heterogenous or homogenous. Heterogenous mixture is when the substances present in the mixture have different phases and the homogenous mixture is when the all the substances are present in the same phase.
Answer to Problem 62A
The sea water is a heterogenous mixture.
Explanation of Solution
The sea water consists of salt, water, and some time debris. The salt and the water in the sea water are present in completely dissolved form, making them a homogenous mixture, but the sand and the debris are present in semisolid and solid form respectively, overall making the sea water heterogenous mixture.
