Boiling point electrical conductivity in aqueous solution solubility in h2o (grams of solid in 100 grams h2o) a low, 65o c poor 3.0 b high 1600o c good 36.0 carl and sally designed an experiment to compare and contrast the properties of covalent and ionic compounds. after designing their experiment, carl and sally tabulated the data in the table seen here. a represents the covalent compound; b the ionic compound. based on their data, it is apparent that carl and sally probably used all of the lab equipment except a/an a) rotary evaporator. b) temperature probes. c) electronic balance. d) conductivity apparatus.
