Water < Acetic Acid < Hydrochloric Acid.
Explanation (Additional info)
To arrange acetic acid, water, and hydrochloric acid in increasing order of acidic strength, we can consider their ability to donate protons (H⁺ ions).
1. Water (H₂O): Water is neutral and has very weak acidic properties, meaning it does not donate protons easily.
2. Acetic Acid (CH₃COOH): Acetic acid is a weak acid that can donate protons but is not as strong as hydrochloric acid.
3. Hydrochloric Acid (HCl): Hydrochloric acid is a strong acid that completely dissociates in water, easily donating protons.
