1. Increase the temperature: Heating the water increases the kinetic energy of the water molecules. This leads to more collisions with the copper sulfate crystals, breaking them apart faster and increasing the rate of dissolution.
2. Stir or agitate the solution: Stirring or shaking the solution constantly removes the dissolved copper sulfate ions from the immediate vicinity of the crystals. This creates a concentration gradient, allowing more copper sulfate to dissolve. Think of it like constantly clearing the space around the crystals, allowing more to dissolve.
