If the water product is formed with the hydrogen ion from the acids, what ion do the bases donate to form H₂O, water?

A) OH+
B) H+
C) OH-
D) H-

1 answer

The ion that bases donate to form water (H₂O) is the hydroxide ion (OH⁻). When an acid donates a hydrogen ion (H⁺), it can combine with the hydroxide ion from the base to form water. Therefore, the correct answer is:

C) OH⁻
