Dye Dissolution and Dispersion: Temperature and Crystal Size Effects

This chemistry practical assignment investigates the factors affecting the rate of dye dissolution and dispersion, specifically focusing on the impact of temperature and crystal size on the dissolution of potassium permanganate in water. The experiment involves dissolving potassium permanganate in water at varying temperatures (hot, room, and cold) and observing the rate of dissolution over time. The results are presented in a table and a graph, demonstrating the relationship between temperature and the rate of dye dissolution. The discussion section explains the chemical reactions involved, such as the reduction of permanganate ions, and how temperature influences the kinetic energy of the ions, thereby affecting the dissolution rate. The assignment concludes that the rate of dye dissolution is directly proportional to the temperature and inversely proportional to the crystal size, supporting the experiment's aim.
