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. OH–
c. H+
d. H-
a. OH+
Bases donate the hydroxide ion (OH–) to form water (H2O). So, the correct answer is b. OH–.
To determine which ion bases donate to form water (H2O), we need to understand the properties and behavior of bases. Bases are substances that can accept protons (H+) or donate hydroxide ions (OH-) in a chemical reaction.
In the case of water formation, bases donate hydroxide ions (OH-) to combine with hydrogen ions (H+) from the acids, forming water molecules (H2O). Therefore, the correct answer is option b. OH–.
To arrive at this answer, we need to know the properties of bases and the general process of water formation.
