make glacial acetic acid

2. Physical Properties Due to its purity, glacial acetic acid has a higher density (1.05 g/cm³) and a different freezing point than diluted acetic acid. Its solidifying characteristic at lower temperatures is a notable feature that distinguishes it from its more diluted counterpart.

Glacial acetic acid has a melting point of 16.6 °C and a boiling point of 118.1 °C. Its high polarity, attributed to the presence of a hydroxyl group (-OH), allows for hydrogen bonding, providing it with a relatively high boiling point for a small organic molecule. It is miscible with water, meaning it can mix in any ratio, which further highlights its versatility as a solvent. Glacial acetic acid displays acidic characteristics, with a pKa of around 4.76, meaning it can donate protons in solution, thus making it a weak acid.

Chromium trioxide, a powerful oxidant, is often encountered in its hexavalent form and is known for its ability to facilitate the oxidation of alcohols, aldehydes, and various organic compounds. The compound appears as a red-orange solid, which is soluble in water and organic solvents. It is widely used in organic synthesis for its selective oxidation capabilities, allowing chemists to transform functional groups with precision. When dissolved in glacial acetic acid, CrO3 exhibits unique properties that can enhance its reactivity and utility in organic reactions.
