Acetic acid water - 3ml/10vials

Acetic acid (CH₃COOH) is a weak organic acid best known as the main component of vinegar (aside from water). When dissolved in water, it produces a slightly acidic solution with a distinctive sour taste and pungent smell. Chemical Properties in Water - Formula: CH₃COOH - Acidity: Weak acid (does not fully dissociate in water). - Dissociation reaction: CH₃COOH  ⇌  CH₃COO⁻+H⁺text{CH₃COOH} ; rightleftharpoons ; text{CH₃COO⁻} + text{H⁺}CH₃COOH⇌CH₃COO⁻+H⁺ - pH range: Typically 2.4–3.4 for concentrated solutions; diluted vinegar is closer to pH 4–5. - Solubility: Fully miscible with water in all proportions. Common Concentrations - Vinegar grade – 4–8% acetic acid in water (safe for food use). - Laboratory grade – 10–99% (glacial acetic acid is ~99%, highly corrosive). - Industrial cleaning or processing – Usually 10–20%. Uses of Acetic Acid in Water - Culinary: Vinegar for flavoring, pickling, and food preservation. - Cleaning: Natural disinfectant and limescale remover. - Laboratory: Solvent, pH adjuster, and buffer preparation. - Industrial: Textile dyeing, photographic development, and polymer production. Safety Considerations - Dilute solutions (like table vinegar) are generally safe for consumption. - Concentrated solutions can cause skin burns, eye damage, and respiratory irritation—should be handled with protective gear. - Always dilute by adding acid to water, not the other way around, to prevent splashing hazards.
