1. Physical Properties

   • Appearance: Colorless transparent crystals or white powder.

   • Solubility: Highly soluble in water (approximately 590 g/L at 20°C), soluble in ethanol.

2. Sour Taste

   • Has a mild sour taste and is commonly used as an acidity regulator in food.

   • Main Uses

   • 1. Food Industry

        • Acidulant: Used in beverages (such as carbonated drinks), candies, jams, etc.

        • Preservative: Inhibits microbial growth by adjusting pH.

        • Antioxidant: Prevents enzymatic browning in fruits and vegetables (e.g., when combined with vitamin C).

        • Pharmaceuticals: Used as a pH regulator (e.g., in effervescent tablets) and anticoagulant (to prevent clotting during blood transfusions).

        • Cosmetics: Adjusts pH value in products like shampoos and skincare items.

        • Cleaning Agents: Removes scale (reacts with carbonates to form soluble substances).

     3. Industrial Applications

        • Component in electroplating solutions, textile processing, metal surface cleaning, etc.

     4. Others

        • Preparation of laboratory buffer solutions (pH 2.1-7.4).
