Question

what happens when a solid is dissolved into a liquid?

solid particles sink down toward the bottom layer of liquid particles

solid particles become evenly dispersed among liquid particles

solid particles become suspended in the middle of liquid particles

solid particles float toward the surface layer of liquid particles

Explanation:

Define the dissolution process

When a solute (solid) dissolves into a solvent (liquid), it forms a homogeneous Mixtures called a solution.

Analyze particle behavior

During dissolution, solute particles separate and intermingle with solvent particles at the molecular level.

Evaluate the options

• Option 1 suggests particles sink, which describes an insoluble suspension, not dissolution.
• Option 2 states particles become evenly dispersed, which is the definition of a homogeneous solution.
• Option 3 suggests suspension in the middle, which is not a uniform molecular mixture.
• Option 4 suggests floating, which describes insoluble particles of lower density.

Answer:

• Solid particles sink down toward the bottom layer of liquid particles
• Solid particles become evenly dispersed among liquid particles (Correct answer)
• Solid particles become suspended in the middle of liquid particles
• Solid particles float toward the surface layer of liquid particles
