What reaction occurs when sodium hydroxide is added to the stearic acid in cyclohexane and water?...
What reaction occurs when sodium hydroxide is added to the stearic acid in cyclohexane and water? How does this change the solubility of cyclohexane in water? Does HCl reverse this reaction when it is added? If so why? Does sodium chloride have the same type of behavior as stearic acid or is it different? Explain why these two solutes are the same or different. (Please answer in your own words.)
