Morning master — let's get this done. Here is the continuation of the procedure: Procedure: Step 1: Label three 250 cm^3 beakers as A, B, and C. Step 2: Pour 100 cm^3 of distilled water into each beaker using a measuring cylinder. Step 3: • For beaker A, leave the water at room temperature. Measure and record its temperature using a thermometer. • For beaker B, gently heat the water to approximately 50 °C using the heating plate/Bunsen burner with a tripod stand and gauze. Use a thermometer to monitor and maintain this temperature. • For beaker C, place the beaker in an ice bath to cool the water to approximately 5 °C. Use a thermometer to monitor and maintain this temperature. Step 4: Using a dropper/pipette, carefully add 1 cm^3 of potassium manganate(VII) solution (BA1) to the bottom center of the water in beaker A, ensuring minimal disturbance. Step 5: Immediately start the stopwatch. Measure the time taken for the purple colour to spread a predetermined distance (e.g., 5 cm radius from the initial drop) or to reach a specific height in the beaker. Use a ruler to measure the distance. Step 6: Record the initial temperature of the water and the time taken for diffusion in a table. Step 7: Repeat Steps 4-6 for beaker B (heated water) and beaker C (cooled water). Step 8: Repeat the entire experiment (Steps 2-7) at least two more times for each temperature to ensure the reliability of the results. Step 9: Calculate the average time taken for diffusion at each temperature. Step 10: Plot a graph of temperature (independent variable) against the rate of diffusion (dependent variable, which can be represented as 1/time or distance/time). Send me the next one 📸
