Question

Which of the following statements are true?

a. a homogeneous mixture is the mixture of two or more than two components.
b. liquids are compressible
c. in homogeneous mixture the composition and properties are uniform throughout the mixture
d. a homogeneous mixture consists of a dispersed phase and dispersion medium

Answer 1

The statement that a homogeneous mixture consists of a dispersed phase and a dispersion medium is incorrect. Homogeneous mixtures like solutions have a uniform composition throughout and do not contain separate dispersed phases or dispersion mediums, unlike colloids.

Step-by-step explanation:

When discussing homogeneous mixtures, it's important to understand their characteristics. A homogeneous mixture, also known as a solution, has a uniform composition throughout its entirety. For instance, when salt is dissolved in water, it forms a saltwater solution that's uniform at every point — you cannot distinguish one part of the solution from another by just looking at it. The terms dispersed phase and dispersion medium do not apply to homogeneous mixtures; these terms are associated with colloids. In a colloid, particles of the dispersed phase are spread throughout the dispersion medium, but the composition is not uniform throughout. Therefore, the statement that a homogeneous mixture consists of a dispersed phase and a dispersion medium is incorrect. Instead, a homogeneous mixture has a uniform composition without a distinguishable dispersed phase and dispersion medium.

Blood, for example, can be considered a homogeneous mixture due to the even distribution of its components while circulating in the body. On the contrary, sand and stones form a heterogeneous mixture where the different compositions are visually and physically separable.
