What is the purpose of the ion exchange resin? a. The ion exchange resin takes out Ca2+ and gets rid of Na which makes the hard water softer. b. The ion exchange resin increases the amount of foam because it made the solution softer instead of hard water and you get more foam with soft water. c. The ion exchange resin replaces the Ca2+ and Mg2+ in hard water with Na+ ions so the cleansing properties of the soap are retained. d. The ion exchange resin removes Ca2+ and Mg2+ out of hard water to make it soft.
