3. Ms. Duncan and Mr. Chartrand have two clear and odorless solutions on the lab bench in front of them. They tell you that one of the substances is a base and the other is an acid. A. What two tests could you conduct to determine which solution is the acid and which is the base? What observations would you make, and how would they be used to conclude which solution is the acid and which is the base? (2 marks) B. You are told that one solution is sulfurous acid, and the other is sodium fluoride. I. Show how these compounds behave in an aqueous solution following the modified Arrhenius theory. II. Put a circle around any compound that is amphiprotic. III. Identify if the substance is monoprotic or polyprotic
