Question

graph the following data below. solubility of compound (g solute/100g water) 0°c 20°c 60°c 100°c kcl 28 34 46 56 kclo₃ 5 8 26 59 also use your graph to predict the solubility of kcl at 40°c and predict the solubility of kclo₃ at 80°c.

Explanation:

Step1: Prepare to graph

We have two sets of data for solubility of KCl and KClO₃ at different temperatures. We will plot temperature on the x - axis and solubility on the y - axis.

Step2: Plot KCl data points

For KCl, we have points (0, 28), (20, 34), (60, 46), (100, 56). Mark these points on the graph.

Step3: Draw line for KCl

Connect the KCl points with a smooth curve. To predict solubility at 40°C, find 40°C on the x - axis and read the corresponding y - value on the curve. Assuming a linear - like interpolation between 20°C and 60°C, the solubility of KCl at 40°C is likely around 40 g solute/100g water.

Step4: Plot KClO₃ data points

For KClO₃, we have points (0, 5), (20, 8), (60, 26), (100, 59). Mark these points on the graph.

Step5: Draw line for KClO₃

Connect the KClO₃ points with a smooth curve. To predict solubility at 80°C, find 80°C on the x - axis and read the corresponding y - value on the curve. Assuming a smooth increase, the solubility of KClO₃ at 80°C is likely around 42.5 g solute/100g water.

Answer:

Solubility of KCl at 40°C is approximately 40 g solute/100g water. Solubility of KClO₃ at 80°C is approximately 42.5 g solute/100g water.
