This crystallization method used in this experiment was batch cooling crystallization. The solution that was used in this experiment was potassium chloride (KCl). The potassium chloride solution was prepared by using 500g of potassium chloride and 1.5L of distilled water. The reason that we make the feed solution become saturated is to minimize the time taken for crystallization to occur. RESULT: From the graph of crystal composition against time, the crystal composition will be increase against the time. A crystal starts to form at 45 minutes with 4.3 g. The slurry solution temperature (℃) at inlet 9.8 ℃ and outlet 28.6 ℃. From the table, temperature drops slowly. QUESTION: Based on this experiment, discuss about any discrepancies and sources of error that influence the reproducibility of the experimental result.
