If the water product is formed with the hydrogen ion from the acids, what ion do the bases donate to form H₂O, water?
a
H-
b
OH¯
c
H+
d
OH+
b. OH¯
Bases donate the hydroxide ion (OH-) to form water (H2O). So, the correct answer is b) OH¯.
Bases donate the hydroxide ion (OH-) to form water (H₂O).
To arrive at this answer, we need to understand the concept of acids and bases. Acids are substances that release hydrogen ions (H+) when dissolved in water, while bases are substances that release hydroxide ions (OH-) when dissolved in water. In the reaction between an acid and a base, the hydrogen ion from the acid combines with the hydroxide ion from the base to form water.
So, the correct answer is b) OH¯, which represents the hydroxide ion.
