    Citric Acid Supplier

    My current citric acid supplier's price for 50lbs has increased from $85 to $ 125 in less than a year. Does anyone have any recommendations for chemical suppliers for the mid-Atlantic region?

    Wow! How long does 50 pounds of citric acid last? I have a 1 pound jar in the fridge...that'll probably last the rest of my life.

    Or a lot of artifical lemonade. Or mozzarella cheese.

    Check with a brew shop or some place that has all the supplies for canning food. It is pretty common and prices will vary all over the place.

    On the other hand if you are using it as a stop bath, just use water and then into the fix. Haven't used a stop bath for film in a couple of years now, no issues from it - your mileage may vary.

    i bought some a year or so on ebay from a shop that sells supplies for soap making, very cheap. i am sorry i don't remember the name, but it shouldn't be hard to find something similar.

    I'm using the citric acid to make sodium citrate developer. 50 lbs can get used up faster than you think.

    I've been getting it from Chemistry Store, but the price has gone up there too. Still, it's quite a bit cheaper than the small quantities from the photochem places. But sodium citrate itself is still only ~$100 for 50lbs.

    I'm curious, is this for kallitypes? I only use about 10-20g/l of citric acid in a 20% solution of sodium citrate, mainly as a ph tweak.

    Yes, it is for kallitypes. I think I will just buy the sodium citrate rather than mix my own.

    do you use the citric in a sodium citrate solution (as a preservative, most likely...) or do you use the citric to produce sodium citrate?
    if it's the latter, would you explain, how this works? i am very interested.
