WebWhat are polyprotic acids? A polyprotic acid is any Bronsted-Lowry acid that can donate more than one proton. While the examples above can only release one proton, many acids have multiple acidic hydrogens. Here are some examples: H 2 SO 4 (sulfuric acid) H 3 PO 4 (phosphoric acid) C 10 H 16 N 2 O 8 (Ethylenediaminetetraacetic acid, or EDTA for ... http://butane.chem.uiuc.edu/anicely/chem102Dfa10/Worksheets/Worksheet20_Polyprotic_Salts_Key.pdf
Worksheet 20 – Polyprotic Acids and Salt Solutions
WebAn acid that contains more than one ionizable proton is a polyprotic acid. These acids undergo stepwise ionization reactions involving the transfer of single protons. The ionization constants for polyprotic acids decrease with each subsequent step; these decreases typically are large enough to permit simple equilibrium calculations that treat ... WebSeveral important acids can be classified as polyprotic acids, which can lose more than one H + ion when they act as Brnsted acids. Diprotic acids , such as sulfuric acid (H 2 SO 4 ), carbonic acid (H 2 CO 3 ), hydrogen … highland park il water

WebJul 23, 2014 · For answer (a) the value of the sum A3 + A2 + A1 + A0 is 0.62; for (b) it is 0.128; for (c) it is 0.10165, and for (d) it is 0.100002. So the best answer is (d). What if you didn't have multiple choice? Then you'd want to draw a graph or a table, taking (say) every integer value of pH and connecting them. Here is such a graph: WebYou get a "higher order" Henderson-Hasselbach equation: p H = ( p K a 1 + p K a 2 + p K a 3 − l o g [ P O 4 3 −] [ H 3 P O 4]) / 3. Assuming the ion concentrations are approximately equal, then pH is merely the arithmetic mean of the pKa's.
