Question

Identify each of the following as characteristic of a solution, colloid, or suspension:a. particles of this mixture remain inside a semipermeable membrane but pass through filters

Accepted Answer

Understand the definitions of solution, colloid, and suspension: A solution is a homogeneous mixture with very small particles that do not settle out. A colloid is a mixture with intermediate-sized particles that do not settle out but can scatter light (Tyndall effect). A suspension is a heterogeneous mixture with large particles that settle out over time. Review the behavior of particles in each type of mixture when interacting with a semipermeable membrane and filters: In a solution, particles are small enough to pass through both semipermeable membranes and filters. In a colloid, particles are small enough to pass through filters but too large to pass through a semipermeable membrane. In a suspension, particles are too large to pass through either a semipermeable membrane or a filter. Analyze the given characteristic: The problem states that the particles remain inside a semipermeable membrane but pass through filters. This indicates that the particles are larger than the pores of the semipermeable membrane but smaller than the pores of the filter. Match the characteristic to the correct type of mixture: Based on the analysis, this behavior is characteristic of a colloid, as colloidal particles are of intermediate size and exhibit this behavior. Conclude that the mixture described in the problem is a colloid, as its particles remain inside a semipermeable membrane but pass through filters.
