Make sodium ascorbate.
« on: March 20, 2020, 01:06:41 PM »
Excuse the ignorance.
I am trying to make sodium ascorbate.
I saw that they do it by mixing ascorbic acid and baking soda. On the wiki I found that they were equal parts. But the ones I saw make a mixture of one teaspoon and half a teaspoon of baking soda.
I have a precision balance, if I weigh equal parts, is it done?
Sorry for the ignorance, but I don't know anything about it, I'm just trying to make "sodium ascorbate" to take in the moment.
Thank you.

Depends on how you define "parts"   :D

AScorbic acid has a molecular weight of 176 g/mol
Baking soda (sodium bicarbonate) has  a molecular weight of 84 g/mol

So the ratio (by mass) of ascorbic acid to sodium bicarbonate is 176 to 84; could be 1.76 g to 0.84 g, or 17.6 g to 8.4 g, or 1.76 lbs to 0.84 lbs. 

Volume as to take into account the density:  1.7 g/mL for ascorbic acid and 2.2 g/mL for sodium bicarbonate.
