Which of the following is the best explanation for how a water softener works?

◦ When hard water passes over a resin in the softener, the Ca2+ and Mg2+ ions in the water bind to the resin in place of Na+ ions.
◦ The softener releases an acid to interact with the Ca2+ and Mg2+ ions in the hard water to neutralize them.
◦ When hard water passes through the softener, the Ca2+ and Mg2+ ions are removed through electrolysis.
◦ The softener releases K+ ions to counteract the Ca2+ and Mg2+ ions in the hard water.
◦ When hard water passes through the softener, the Ca2+ and Mg2+ ions precipitate out as Mg(OH)2 and Ca(OH)2.
