Question

Use the solubility curve above to answer the following: If I add 130 g of potassium iodide to 100 g of water at 10°C, how would you describe that solution? *

A. unsaturated

B. saturated

C. supersaturated

Answer 1

solution of KI becomes saturated at 10 degrees when around 135-138g KI are added to 100 g of water, so it should be still unsaturated, A. unsaturated (although it is very close to saturation)
