Assessing the rate of dissociation at high density requires master-equation calculations to elucidate the contributions of ladder climbing. 0000014740 00000 n A strong acid is an acid which is completely ionized in an aqueous solution. Carbonated water is a solution of carbonic acid (H2CO3). Someone told me though, that because it's a weak-acid, it doesn't matter how many ions it has, and that C a C l X 2 will still have the highest elevation boiling point. In this video we will look at the equation for H3PO4 + H2O and write the products. 4. how much liquid containing 6% boric acid should be mixed with 2 quarts of a liquid that is 15% boric acid in order to obtain a solution that is 12% boric acid? The balanced dissociation for I know H3PO4 is weak so it doesn't dissociate, so what I got was H3PO4 (aq) + OH^- (aq) -> 2H^+ (aq) + PO4^3- (aq) + H2O(l) But in my next question it asks to calculate the heat of the rxn for 1 mol of product, but in the Standard Enthalpies I can't find PO4, leading me to believe that I did something incorrectly.
