B)The hard ions are all trapped in the softener,which filets out all the ions.
C)The ions in the water softener are softened by chemically bonding with sodium.
D)The sodium is removed from the water,making the water interact less with the soap molecules.
E)none of the above

Question

Quizplus · Accepted Answer

A water softening unit works by exchanging hard ions (such as calcium and magnesium) in the water with ions that do not interact as strongly with soaps (such as sodium or potassium). This exchange typically happens through a process called ion exchange, where the hard ions are trapped on an ion exchange resin and replaced with ions like sodium, which make the water softer and less likely to leave soap scum.
