Higher T will have a higher boiling point. Thanks a ton guys.. Previous question Next question. Thus the product of the acid constant for a weak acid and the base constant for the conjugate base must be Kw, and the sum of p Ka and p Kb for a conjugate acid-base pair is 14. Polyprotic acids are those with more than one acidic proton. The logarithmic constant (pKa) is equal to -log10(Ka). The pKa values for organic acids can be found in Appendix II of Bruice 5th Ed. Na3PO4 is the reaction product of the complete neutralisation of H3PO4 ( a weak acid) with NaOH(a strong base) The salt Na3PO4 will be basic salt. Phosphate ions are used as a buffer because there are three protonated forms (H3PO4, H2PO4-, and HPO42-) that have pKa in the correct . 1. The anion is phosphate, PO4^-3 and (it has a charge of -3). In this case find and write both names as found on the Common Ion Table.-----------------------------For a complete tutorial on naming and formula writing for compounds, like Sodium phosphate and more, visit:http://www.breslyn.org/chemistry/namingDrawing/writing done in InkScape. Rock - if you dont mind me asking what was your DAT score? in these problems, being on the wrong side of neutral is the red flag that you picked the wrong direction (gaining/losing a proton). Trisodium phosphate solution. Aweak acidis an acid that ionizes only slightly in an aqueous solution.
