Question

Identify each of the following as characteristic of a solution, colloid, or suspension: a. a mixture that cannot be separated by a semipermeable membrane

Accepted Answer

Step 1: Begin by understanding the three types of mixtures: solutions, colloids, and suspensions. A solution is a homogeneous mixture where the solute is completely dissolved in the solvent. A colloid is a mixture where the particles are larger than in a solution but do not settle out. A suspension is a heterogeneous mixture where particles are large enough to settle out over time. Step 2: Recall the property of separation by a semipermeable membrane. A semipermeable membrane allows small particles, such as ions or molecules in a solution, to pass through, but it blocks larger particles like those in colloids or suspensions. Step 3: Analyze the given statement: 'a mixture that cannot be separated by a semipermeable membrane.' This means the particles in the mixture are too large to pass through the membrane. Step 4: Compare this property to the characteristics of solutions, colloids, and suspensions. Solutions can pass through a semipermeable membrane because their particles are very small. Colloids cannot pass through because their particles are larger, but they do not settle out. Suspensions also cannot pass through, but their particles are large enough to settle out over time. Step 5: Based on the inability to pass through a semipermeable membrane and the lack of settling, identify the mixture as a colloid.
