1. Hydrochloric acid (HCl)
- When HCl dissolves in water, it completely dissociates into hydrogen ions (H+) and chloride ions (Cl-).
2. Sodium hydroxide (NaOH)
- NaOH dissociates in water to form sodium ions (Na+) and hydroxide ions (OH-).
3. Sulfuric acid (H2SO4)
- H2SO4 is a strong acid that dissociates into two hydrogen ions (2H+) and one sulfate ion (SO42-).
4. Acetic acid (CH3COOH)
- Acetic acid undergoes partial dissociation in water, forming hydrogen ions (H+) and acetate ions (CH3COO-).
5. Ammonium hydroxide (NH4OH)
- NH4OH dissociates into ammonium ions (NH4+) and hydroxide ions (OH-).
These are just a few examples of many molecular compounds that undergo ionization in water. The ability of a molecular compound to ionize in water depends on its chemical structure and the polarity of the water molecule.
