Answer 1

A solution is transparent blue.

The answer is d) Both a colloid and a true solution. Because for a colloid, particles are very small and can scatter light, which is why it appears to be a colloid.

True Solution is a homogeneous mixture of two or more materials with a particle size of less than 10-9 m or 1 nm dissolved in the solvent

since we don't know whether the mixture is homogeneous or heterogeneous, we can't assume whether it can be a true solution or a colloid. So the answer is D.

Answer 2

Answer:

Transparent blue solution is (c) true solution.

Explanation:

• A true solution is homogeneous mixture which is transparent. Here, the solute and solvents are properly mixed in the liquid phase. Size of particle is less than 1 nanometre. True solution do not show Tyndall effect. Example: sugar in water.

• Colloidal solution is a type of mixture where solute is uniformly distributed in solvent. It is a heterogeneous mixture and translucent in appearance. Particle size is 1-1000 nanometres. There is no sedimentation of particles. Brownian motion and Tyndall effect is visible in colloids. Example: starch in water.

• Suspension is a type of heterogeneous mixture where solute does not get dissolved, rather is gets suspended in the solvent. Sedimentation of solute can be seen. The solution is opaque. Size of particles are more than 1000 nanometres. Example: soil in water.
