Final answer:
Magnesium hydroxide is basic in nature, while nitric acid, hydrochloric acid, and acetic acid are acidic.
Explanation:
Magnesium hydroxide is basic in nature.
Acids release H+ ions in water, while bases release OH- ions. Magnesium hydroxide, being a base, will release OH- ions in solution, making it basic.
In contrast, nitric acid, hydrochloric acid, and acetic acid are acids which release H+ ions and are therefore acidic.
