Question

mixture a was made by mixing different components together, but it appears to have one phase. which term best categorizes mixture a?
○ colloid
○ solution
○ emulsion
○ suspension

Explanation:

• A solution is a homogeneous mixture with one phase (uniform composition throughout).
• A colloid has a dispersed phase and a continuous phase, often showing the Tyndall effect but still has a more uniform appearance than suspensions/emulsions but is not as homogeneous as a solution in terms of particle size and phase uniformity for this context.
• An emulsion is a type of colloid with two immiscible liquids (two phases, e.g., oil - water emulsion).
• A suspension has visible particles that settle over time and has two phases (the solid particles and the liquid medium). Since Mixture A has one phase, it is a solution.

Answer:

B. solution
