Question

when you added copper sulfate crystals in a beaker of water, it was dispersed. which process did this experiment demonstrate? a. osmosis b. diffusion c. hypotonic d. plasmolysis

Explanation:

• Osmosis is the movement of water molecules across a semi - permeable membrane. Here, it is copper sulfate crystals in water, not water movement across a membrane.
• Diffusion is the movement of particles (solute particles in this case, copper sulfate ions) from an area of higher concentration (where the crystals are) to an area of lower concentration (the water) until equilibrium is reached. This is what happens when copper sulfate crystals disperse in water.
• Hypotonic is a term used to describe a solution's concentration relative to another solution (e.g., a cell's interior). It is not a process.
• Plasmolysis is the shrinkage of a cell due to water loss when placed in a hypertonic solution. It is not relevant to the dispersion of copper sulfate in water.

Answer:

B. diffusion
