Acetic acid (CAS 64-19-7), is a fundamental organic acid used across chemical, pharmaceutical, food, and laboratory industries. One of its most important physical properties is its excellent solubility in water, which directly influences how it is stored, transported, formulated, and applied in industrial processes.
Does acetic acid (GAA) solution dissolve in water?
Acetic acid (CH₃COOH) exhibits excellent solubility in water, being completely miscible with water in any proportion. This property stems from the carboxyl group (-COOH) in its molecular structure, which possesses strong polarity and hydrogen bonding capabilities. When Acetic Acid (GAA) dissolves in water, its carboxyl groups interact with water molecules via hydrogen bonds. Simultaneously, some acetic acid molecules ionize into acetate ions (CH₃COO⁻) and hydrogen ions (H⁺), imparting a weakly acidic nature to the solution (pH approximately 2.4 at a concentration of 1 mol/L).

uses of acetic acid (GAA CAS 64-19-7)
The high solubility of Acetic Acid (GAA CAS 64-19-7) Solution enables its widespread application in the food industry (as a souring agent), chemical synthesis (e.g., cellulose acetate production), and laboratories (for buffer solution preparation).
Glacial Acetic Acid (GAA) is acetic acid with a concentration ≥99%, named for its low-temperature solidification into ice-like crystals. Its applications fall into four major categories:
Industrial Applications
Synthesis of vinyl acetate (used in paint and adhesive manufacturing), terephthalic acid (raw material for PET plastics), etc. Approximately 60% of global glacial acetic acid is consumed in chemical production.
As a pH adjuster in textile dyeing to ensure uniform dye adsorption.
Laboratory Settings
Acetic Acid (GAA CAS 64-19-7) solution is used to prepare buffers (e.g., acetic acid-sodium acetate buffer, pH 4.0-5.5) for biochemical experiments.
A 3%-5% dilution is typically employed for protein precipitation.
Medical Applications
Treating plantar warts: Apply 80%+ concentration directly to the wart for cauterization. Professional administration is required to prevent skin burns.
Disinfecting otitis externa: Dilute to 2%-3% for use in inhibiting fungi and bacteria.
Food Additives
Food-grade acetic acid (GAA CAS 64-19-7) solution (E260) is used in pickling and seasonings, with a safe limit of 10g/kg.
Storage and Transportation of Acetic Acid (GAA CAS 64-19-7)
- Storage: GAA should be stored in sealed containers in a cool, dry, well-ventilated area, away from sources of ignition and oxidizing agents.
- Transportation: Follow hazardous chemical transportation regulations to prevent leakage and damage.
