Is CH3COOH (acetic acid) dissolved in water?

Dec 10, 2025 Leave a message

CH3COOH, also known as acetic acid CAS 64-19-7, is a weak organic acid that plays a crucial role in the context of electrolytes and the hydrolysis of salts. It is a common compound found in various chemical and biological processes.

 

Is CH3COOH (acetic acid) dissolved in water?

CH3COOH (acetic acid) is a weak acid that is soluble in water and other polar solvents. The solubility of glacial acetic acid in water is influenced by various factors, including temperature, pressure, and the presence of other solutes. At room temperature (25°C), the solubility of glacial acetic acid in water is approximately 18 g/100 mL. This means that if you add 100 mL of water to 18 g of glacial acetic acid, the solution will be saturated. As the temperature increases, the solubility of glacial acetic acid in water also increases. For example, at 60°C, the solubility increases to approximately 50 g/100 mL.
