vitamin c

[billybobjoe]

I have searched the forums and found no topic directly pertaining to this.

My question is what is the concentration of citric acid in over the counter vitamin c powder. Are there any anti-clumping agents present or inert binders? I have read the ingredients of the bottles and just says "contains: citric acid."

If there is inert binders or anti-clumping agents present how would I got about separating them, assuming you know what they are. Any and all help is appreciated.

Perhaps you have confused citric acid with ascorbic acid (vitamin C).

So which do you want. Citric acid or ascorbic acid?

If it is citric acid you are after, using vitamin C powder it probably a very expensive way of going about it.
Citric acid can normally be found in the supermarkets. Around here it is on the shelves amongst ground nutmeg and other spices.
I've seen it sold as Citric Acid and Sour Salt.

The Brand I've got at the moment is McKenzie's. Although I think this is an Australian brand.

Pool and spa suppliers sell Vitamin C powder (Ascorbic Acid) at $5 for 4 ounces.

Citric Acid is available in the canning supplies section of the grocery store.

The only time I've ever seen the two mixed is in an anti-darkening additive for home canning fruit.

Thank you all for your help. I am in fact after citric acid, and no, I didn't get my acids mixed up. I always hear about pool and spa suppliers having this miraculous selection of goodie, my idea of a candy store, but to my dismay I found chlorine tablets (some form of chlorate I assume) and low test peroxide 14%.

Vitamin C = ascorbic acid, not citric acid

It sounds to me like you did get your acids mixed up.

By the way, pool tablets = calcium hypochlorite.

Pb1 – I think what he was trying to do was extract citric acid out off vitamin c powder, although it is possible it isn’t very practical.

It would probably be easier to extract it from lemon juice or sour sugar.

Billy - maybe you should research into what chemicals are in products more thoroughly. One day if you get something mixed up with another (eg. hypochlorite and chlorate in pool tablets) you could seriously injure or kill yourself.
