Question

What statement is most appropriate when your friend plans to purchase a water softener?

a) Hard water makes more bubbles with less soap than soft water and is more desirable.
b) Soft water leaves a ring in the tub and a gray residue in the wash, which is undesirable.
c) Soft water appears to aggravate hypertension, which is undesirable.
d) Soft water has higher concentrations of calcium and magnesium than hard water, which is desirable.

Answer 1

d) Soft water has higher concentrations of calcium and magnesium than hard water, which is desirable.Soft water has higher concentrations of calcium and magnesium than hard water, which is desirable for cleaning purposes and extends the lifespan of plumbing systems.

Step-by-step explanation:

When your friend plans to purchase a water softener, the most appropriate statement is:d) Soft water has higher concentrations of calcium and magnesium than hard water, which is desirable.Soft water has lower levels of calcium and magnesium compared to hard water. This makes it easier for soap to lather and reduces the formation of scale in pipes and fittings. Soft water is more desirable for cleaning purposes and extends the lifespan of plumbing systems.

When your friend plans to purchase a water softener, the most appropriate statement is that soft water requires less soap for the same cleaning effort, as soap is not wasted bonding with calcium ions. Soft water extends the lifetime of plumbing by reducing or eliminating scale build-up in pipes and fittings. Water softening is usually achieved using lime softening or ion-exchange resins, and it results in water with fewer dissolved minerals such as calcium and magnesium.
