Question

characteristics of each in the table.
\tsuspensions\tsolutions\tcolloids\tparticles

Explanation:

To fill the table about the characteristics of solutions, colloids, and suspensions (assuming the "particles" column is about particle size or other properties), we can use the following information:

For the "particles" (let's assume particle size as the property here):

• Solutions: Particle size is typically less than \(1\,\text{nm}\) (or \(10^{-9}\,\text{m}\)). The solute particles are individual ions or molecules, so they are very small and uniformly dispersed.
• Colloids: Particle size ranges from \(1\,\text{nm}\) to \(1000\,\text{nm}\) (or \(10^{-9}\,\text{m}\) to \(10^{-6}\,\text{m}\)). The particles are larger than in solutions but still small enough to remain dispersed and not settle quickly (e.g., protein molecules, micelles).
• Suspensions: Particle size is greater than \(1000\,\text{nm}\) (or \(10^{-6}\,\text{m}\)). The particles are large enough to be visible under an optical microscope and will settle over time if left undisturbed (e.g., sand in water, muddy water).

If we structure this into the table (rows: suspensions, solutions, colloids; column: particles, with particle size as the characteristic):

	Particles (Size)
Solutions	\(< 1\,\text{nm}\) (uniform, no settling)
Colloids	\(1 - 1000\,\text{nm}\) (dispersed, slow settling)

If the "particles" column refers to other characteristics (e.g., visibility, Tyndall effect, stability), here’s how we can fill it:

Visibility of Particles:

• Solutions: Particles are not visible (even under a microscope) because they are individual molecules/ions.
• Colloids: Particles are not visible to the naked eye but may be visible under an electron microscope (due to larger size than solutions).
• Suspensions: Particles are visible to the naked eye or under an optical microscope.

Tyndall Effect (Scattering of Light):

• Solutions: No Tyndall effect (light passes through without scattering).
• Colloids: Show Tyndall effect (light is scattered by the dispersed particles).
• Suspensions: May show Tyndall effect (if particles are large enough to scatter light) but often appear opaque due to large particle size.

Stability:

• Solutions: Stable (particles do not settle, uniform composition).
• Colloids: Relatively stable (particles remain dispersed, may settle very slowly).
• Suspensions: Unstable (particles settle over time, requiring stirring to remain dispersed).

Depending on the intended characteristic for the "particles" column, you can choose the relevant property (size, visibility, stability, Tyndall effect) to complete the table. If the original table has a specific characteristic in mind (e.g., particle size, as is common in chemistry for classifying mixtures), the first version (particle size) is the most standard.
