    How stupid can I get? I ordered chemicals for salt prints, and for some unknown reason I fumbled and bought Pro-Analysi grade Ascorbic Acid instead of Citric Acid...

    I suppose Vitamin C does nothing for salt prints - so, any good ideas for use of the ascorbic acid? :D

    If you have no use for it in a developer then take a 1/4 teaspoon a day until it is all gone.

    Actually, it's me who's being stupid now! I misread your post and thought you said you ordered ascorbic acid instead of vitamin C, not citric acid.

    You can use Ascorbic Acid for any recipe that calls for Sodium Ascorbate. My favorite is Mytol, a great Xtol substitute.

    Replace 1g Ascorbic Acid with 1.1248g of Sodium Ascorbate, or 1g Sodium Ascorbate with 0.8890g Ascorbic Acid.

    You can use ascorbic acid or sodium ascorbate in a wide variety of conventional B&W film and paper developers, including Mytol, E-76, PC-Glycol, PC-TEA, DS-10, and DS-12 for film; and E-72, DS-14, and DS-15 for paper. There are more such developers, too, if you do some digging. In a pinch, you can use sodium ascorbate as a substitute for hydroquinone in many developers that use hydroquinone. I don't recall the exact substitution ratio offhand, though, and the two substances aren't exact workalikes. They are both superadditive with both phenidone and metol, though. To get sodium ascorbate from ascorbic acid, put 89.0g ascorbic acid in water then add 42.4g sodium bicarbonate until fizzing subsides for every 100g of sodium ascorbate you need. (Scale appropriately for your formula.)

    Thank you for your advice, ladies and gents! I have to do some digging on the chemical recipes given and if nothing seems doable, I'll take a 1/4 tsp a day and hope it'll clear any further chemistry confusions of mine, in the future. :D

    Doesn't it cure rickets?

    It seems rickets is caused by vitamin D deficiency, but any sea pirate knows that ascorbic acid at least cures scurvy! See below.

    "When there is a shortage of VITAMIN C, various problems can arise, although scurvy is the only disease clinically treated with vitamin C. However, a shortage of vitamin C may result in "pinpoint" hemorrhages under the skin and a tendency to bruise easily, poor wound healing, soft and spongy bleeding gums and loose teeth.

    Edema (water retention) also happens with a shortage of vitamin C, and weakness, a lack of energy, poor digestion, painful joints and bronchial infection and colds are also indicative of an under-supply."

    Just so you know when to take your teaspoons... :wink:

    It prevents scurvy.

    IIRC, rickets results from a vitamin D deficiency.

    EDIT: beaten to the punch!
