Explanation:
Bases:
- Bases are substances that can accept protons or donate hydroxide ions in a chemical reaction.
- They have a pH greater than 7.
- Common bases include metal hydroxides and certain carbonates.
Options:
- Magnesium hydroxide: This is a base as it contains the hydroxide ion (OH-) which can accept protons.
- Calcium hydroxide: This is also a base for the same reason as above.
- Calcium carbonate: This is not a base. Calcium carbonate is a salt and does not release hydroxide ions in solution to make it a base.
- Sodium hydroxide: This is a base as it contains the hydroxide ion (OH-) which can accept protons.
Conclusion:
- Among the given options, calcium carbonate (option C) is not a base. It is a salt composed of calcium ions and carbonate ions, and does not exhibit typical base properties like releasing hydroxide ions in solution.
