Acetic acid 3% is a dilute aqueous solution of acetic acid, commonly known as vinegar, widely used in food preservation, cleaning, and laboratory applications.
🏭⚗️ Production
Industrial acetic acid is produced mainly by methanol carbonylation or fermentation processes. The 3% solution is prepared by diluting concentrated acetic acid with water under controlled conditions, both industrially and in laboratories.
🔬 Properties
Acetic acid 3% appears as a clear, colorless liquid with a pungent vinegar-like odor. It is miscible with water and has a mild acidic taste. The low concentration makes it less corrosive compared to concentrated forms.
🧪 Applications
It is widely used as a food preservative and flavoring agent, in household cleaning products, and as a mild acid in laboratories for titrations and pH adjustments.
⚠️ Safety
At 3%, acetic acid is generally safe but may cause mild skin or eye irritation upon prolonged contact. It should be handled with basic precautions and stored in a cool, dry place away from strong oxidizers.
