Citric acid is a translucent or white solid which is available as a granular powder. Citric
acid crystallizes from hot concentrated aqueous solutions in the form of large rhombic
prism-shaped crystals containing one water molecule, which it loses when heated at
100 ºC, temperature at which it simultaneously melts.
Uses:
- Citric acid is used for the chemical cleaning of osmosis membranes (descaling action; in 2.5% solutions it is effective within a 30 minute minimum contact time and at 35º)..
- Due to its descaling action, citric acid is used for the chemical cleaning of dialysis equipment (the solution depends on the equipment manufacturer’s recommendations).
