Worked Solution & Example Answer:A student carried out an experiment to investigate the solubility of copper sulfate in water - Junior Cycle Science - Question f - 2018
Step 1
Describe the effect of increasing the temperature on the solubility of copper sulfate.
Answer
Increasing the temperature of the water generally leads to an increase in the solubility of copper sulfate. As the temperature rises, the kinetic energy of the molecules increases, allowing more copper sulfate crystals to overcome the intermolecular forces that hold them together, thus dissolving more of the solute in the solvent.
Step 2
Describe how to make a solution saturated.
Answer
To make a solution saturated, you need to add copper sulfate to warm water and stir until no more solute dissolves. This means you should continue adding the solute until the solution reaches a point where additional copper sulfate remains undissolved at the bottom of the container. Maintaining the solution at a certain temperature can help achieve saturation more effectively.
