So elevation in boiling point will be above a boiling point of water for all solutions. Conjugate Acid-Base Pairs. 1 Answer. You will be notified when your spot in the Trial Session is available. As with acids, bases can either be strong or weak, depending on their extent of ionization. Table 2. nKa Values / Acid-Salts Sodium Hypochlorite Calculate the pH of 0.10 M NaClO solution. The normal freezing point of water is 0.0C. You are using an out of date browser. For a better experience, please enable JavaScript in your browser before proceeding. TABLE OF CONJUGATE ACID-BASE PAIRS Acid Base K a (25 oC) HClO 4 ClO 4 - H 2 SO 4 HSO 4 - HCl Cl- HNO 3 NO 3 - H 3 O + H 2 O H 2 CrO 4 HCrO 4 - 1.8 x 10-1 H 2 C 2 O 4 (oxalic acid) HC 2 O 4 - 5.90 x 10-2 [H 2 SO 3] = SO 2 (aq) + H2 O HSO Equation or enables us to calculate the base constant of a conjugate base from the acid constant of the acid, and vice versa. pKa: A quantitative measure of the strength of an acid in solution; a weak acid has a pKa value in the approximate range 2 to 12 in water and a strong acid has a pKa value of less than about 2. Solution is formed by mixing known volumes of solutions with known concentrations. . 1 x 10-14 = K a*Kb Ka = 1x10-14/1.8x10-5 = 5.6 x 10-10 (or look up in table) So, Calculate the pH of a 0.300 M Na3PO4 solution. Other names - Trisodium phosphate, Sodium orthophosphate, Tribasic sodium phosphate. Screen capture done with Camtasia Studio 4.0. [citation needed] This mixture is particularly effective for removing mildew, but is less effective at removing mold. The high-temperature phases of sodium orthophosphate, HT-Na3PO4, and of the solid solutions (Na2SO4)x(Na3PO4)1-x are characterized by their plastic crystalline state with dynamically disordered PO43- and SO42- anions and a remarkably high cation conductivity.
