What is Citric Acid?

Citric acid is a weak organic acid that is naturally found in citrus and juicy fruits such as lemons, limes, oranges, grapefruit, apples, pears and berries. Although it is often associated with sweet-tasting fruit, citric acid appears as odourless and colourless crystals.

  • Appearance: Solid
  • Formula: C6H8O7
  • Melting point: 153°C
  • Boiling point: 175°C
  • Density: 500-950 kg/m3 CAS No.: 77-92-9

Uses of Citric Acid

Citric acid is used in a wide range of applications, including:

  • Food flavouring, colouring or preservation. It is also often added to products like ice cream as an emulsifying agent to stop fats from separating
  • Cleaning and chelating agents, particularly in the home bathroom and kitchen cleaning products. It is also used to remove rust from steel in the industry
  • Bath bombs, where it reacts with baking soda to release carbon dioxide. This what causes the bath bomb to fizz
  • Photographic development to neutralize the alkaline developing solutions
  • pH balancing for pharmaceuticals
  • Substitution of nitric acid in industry.

Production of Citric Acid

Citric acid at room temperature is a white crystalline powder in either anhydrous or monohydrate forms. Monohydrate citric acid can be easily dried by heating the crystals at 78oC, but higher temperatures will result in decarboxylation. This compound can dissolve in water, ethanol, ether, DMSO and other solvents.

Citric Acid Side Effects

Although it is a weak acid, citric acid can cause adverse effects in humans if inhaled or ingested in large, concentrated quantities over a long-term period. It is crucial that all handling and storage guidelines are properly adhered to at all times regarding this product.

Side effects of consuming too much citric acid include stomach cramps, nausea, diarrhoea or vomiting and increased sweating or swelling.
