  1. Thank you very much. Do you happen to know the correct chemical equations for the sodium citrate synthesizing method you described? Based on the information I read here: http://en.wikipedia.org/wiki/Sodium_citrate When someone just says "Sodium Citrate" they are talking about "Monosodium citrate" correct? Na2CO3 + C6H8O7 --> NaH2(C3H5O(COO)3) is NaH2(C3H5O(COO)3) the correct molecular formula? Will someone have a peak at this? http://dmwdev.com/science_cu_sulfate.html Does that large amount of Copper Precipitate mean that all of my Sulfuric Acid has been converted into Copper(II) Sulfate? Should I take the copper electrodes out now? Should I filter that copper muck out?
  2. I am trying to create some benedict's solution. The ingredients: Copper(II)Sulfate: Created with copper and sulfuric acid. as described here http://www.scienceforums.net/forum/showthread.php?t=10342 Sodium Carbonate: Help! how should I get this? Sodium Citrate: Help! how should I get this? Sodium Citrate dihydrate After All Ingredients are gathered I found this from searching on the internet. But I am having a little bit of trouble understanding this. When they say 173 g of "sodium citrate dihydrate" would this include the mass of 2 H2O molecules with each molecule of Sodium citrate dihydrate? and when thay say "17.3 g copper sulfate pentahydrate in 100 mL of water" is the 100ml of water beyond the 5 water molecules for each molecule of Copper sulfate? (17.3g of Coper Sulfate) + (6 molecules of water for each molecule of coper sulfate) + (an additional 100ml of water)
