Acetate used to treat calcific deposits is which charge?

• A. Negatively charged, treats calcific deposits
• B. Positively charged, used to promote healing
• C. Neutral charge, used for analgesia
• D. Positively charged, used to treat pain

Answer: (A)

The key idea is that this treatment uses ions delivered into tissue by iontophoresis, and the ion chosen for calcific deposits is acetate, which is negatively charged. Because like charges repel, the negatively charged acetate ions are placed under the negative electrode and driven into the surrounding tissue to reach and help dissolve the calcium deposits. This is why the correct description is that acetate used for calcific deposits is negatively charged.
