Making a stock solution of ascorbic acid?

26 October 2021 1 2K Report

Hello, I need to make a 20X solution of ascorbic acid. I currently have 99%+ ascorbic acid solid and have to turn it into 20X concentration stock solution. I'm so lost and cant seem to find literature on it. Any help would be greatly appreciated.

Shail K Chaube

Define X and mention the details of Ascorbic acid (grade) you have. Whether you are using its stable form? If not then instead of making 20X as a stock solution, prepare a fresh solution in water every time. Ascorbic acid should not be stored as it is highly unstable (until you use its stable form for your experiment).

Good luck
