  1. I am working on a project and need your help Can anyone point me to a comprehensive list of the PhytoChemical FAMLIES i.e. alkaloids, glycosides, polyphenols, and terpenes Thank you Brad
  2. Hello everyone I have bit off a little more than I can chew with a project i am working on. First off it should be known I AM NOT a chemist, far from it, so I am a little out of my league with this project. I am trying to find out what are the names of the CATEGORIES of chemical compounds found in plants, both on the primary and secondary metabolite levels. I am NOT looking for the names of the individual compounds. For example I know on the primary metabolite side, Carbohydrates is one category ( am not looking for all the names of the sugars ie mono, di polysacarides, and thei
  3. Ok if i understand my chemistry correct a hydroxide has a pKa value of 15.7 so that means it can form an "ionic bond"? with anything less than a pH of 15.7 i.e. phosphoric acid = 50/50 tri and di, Phosphate at 2. 148, 50/50 Di and mono @ ph7.199, 50/50 of mono and phosphate at ph 12.35 Now my investigation shows that caffeine is a base and has a pKa value of 14? is this correct? Now from what I have read if you take caffeine and react it with citric acid you get caffeine citrate? is this correct? (when I mean react, i mean put the caffeine in water along with the citric acid then eva
  4. The amount of free hydrogen ions? Sorry I am not a chemist nor have taken any chemistry classes. My gut instinct is that it is a total of the sum so the ph would down from 4 to 4 . But again this is my gut instinct and I am no chemist. I am a language instructor.
  5. If I have an acid say phosphoric acid which has a ph of 4, and a citric acid with a ph of 4 will the ph still be 4, (because both are independant) or will the ph go down to say 3 because the sum of the 2 parts are greater than the whole? please let me know Thanks Brad
  6. Hello everyone Quick question, given 1 liter solution of phosphoric acid in water, which has a ph of 2.47, how much TriSodium citrate would be needed to drop the ph from 2.47 to 3.3 TIA Brad
  7. Hello Everyone I am not a chemist nor have much experience in the formulas. I have tried to solve this and I can not get it to work out. I am trying to find the Ph of 8.10581454g of 85% phosphoric acid in 18927.1ml of water. Here is my math Ok can some one please tell me if I did this right I have 8.105807928 grams of 85% Phosphoric acid. Now Phosphoric acid has 97.995287 molecular mass So if i divide 8.105870928 by 97.995287 I get .082716304 moles is this correct? Then since I have 18.9271 L So if I take .082716304 and divide by 18.9271 i get .00437 for
