Reef Chemistry Question of the Day 288
Deionizing resins used in an RO/DI have ionic charges that are permanently attached to the resin, and other ionic charges that are free to move around and potentially come out of the resin.
Which of the following ions comprise the free to move around ions in new DI resin?
A. Sodium (Na+) and chloride (Cl-)
B. Calcium (Ca++) and sulfate (SO4--)
C. Hydrogen ion (H+) and chloride (Cl-)
D. Hydrogen ion (H+) and hydroxide (OH-)
E. Sodium (Na+) and hydroxide (OH-).
Good luck!
