Applicant's summary and conclusion
- Conclusions:
- Glycolic acid 70% solution can act as reducer in the presence of strong oxidisers.
- Executive summary:
Glycolic acid 70% solution can act as reducer in the presence of strong oxidisers.
In aqueous solution the reduction potential is a measure of the tendency of the solution to either gain or lose electrons when it is subject to change by introduction of a new species. A solution with a higher (more positive) reduction potential than the new species will have a tendency to gain electrons from the new species (i.e. to be reduced by oxidizing the new species) and a solution with a lower (more negative) reduction potential will have a tendency to lose electrons to the new species (i.e. to be oxidized by reducing the new species). Glycolic acid has reducing potential (the tendency to lose electrons) only in solution.
