Use the "like dissolves like" principle to explain the solubility experiments that you did with ethanol, pentanol, kerosene, and water.
Answer: A small puddle of each substance was placed on the reaction surface. Next, a sample of KI was placed in each puddle. KI is ionic and polar so it would dissolve in polar solvents. The polarity of the solvents would be ranked bases on how quickly the KI dissolved.
