Question

blood is a mixture of a variety of materials. some of the materials are dissolved in the fluid portion of blood. other materials, such as blood cells, do not dissolve but move along with the blood. for these reasons, blood is an example of which type of mixture? a. a solvent b. a solution

Explanation:

A solvent is a substance that dissolves other substances. A solution is a homogeneous mixture where the solute is uniformly dissolved in the solvent. Blood has some undissolved components (blood - cells) along with dissolved materials, so it is not a solvent or a solution. Blood is a heterogeneous mixture as it has different phases (dissolved substances in the fluid part and undissolved cells). But among the given options, since it has both dissolved and non - dissolved components and is not a pure solvent or solution, we need to understand the definitions of the options. A solvent is a single substance used for dissolving, and a solution has all components uniformly dissolved. Blood has particles (blood cells) that do not dissolve, so it is not a solution or a solvent.

Answer:

None of the above options are correct as blood is a heterogeneous mixture, but if we have to choose from the given options, neither A. a solvent nor B. a solution is correct.
