The material specification is 'powder or crystals', which means it can vary from batch to batch. Ascorbic acid can donate electrons, facilitating the reduction of protons (H?) to hydrogen gas (H?). Its ability to undergo oxidation makes it a suitable candidate for these hydrogen evolution reactions. This product has not been tested internally for this application. Given the high purity of this material, it is likely suitable, but this would need to be determined by the end user.

General description
L-Ascorbic acid, also known as vitamin C, is a water-soluble vitamin. It is naturally present in a variety of foods such as citrus fruits and vegetables. It is present only in minimal amount in milk.
Application
Biochem/physiol Actions
L-Ascorbic acid (Vitamin C) acts as a potential anti-oxidant and reducing agent. It prevents bacterial mutagenesis induced by N-nitroso compounds. In plants, vitamin C elicits several cellular processes such as growth, apoptosis, pathogen responses, hormone responses, flowering and senescence, and protection against environmental stresses. Vitamin C deficiency is associated with the development of scurvy, prominent - gingivitis, perifollicular hemorrhages, poor wound healing, petechiae and ecchymosis.
Other Notes
