Acid or Brnsted base can be neutral molecules, positive ions or negative ions. Various Brnsted acids and their diversion base are given in the table below. General Brnsted acid and acid base diversion base H3O + H2O H2O OH-OH-O2-HCl Cl-H2SO4 HSO4-HSO4-SOO4-SO42-NH4+NH3 NH3 NH2- Compounds can be both Brnsted acid and Brnsted base. 9.0 and 11.0. Arrange the acids, HX, HY and HZ in order of increasing acid strength. The strongest acid would have the weakest conjugate base. Weaker bases (at equal concentrations) will have lower pH values (they are less basic). The base strengths must be X-< Y-< Z-The conjugate acids will have the reverse trend: HZ < HY < HX 4.

Examine the titration curves in Model 1. Identify the analyte and titrant that reacted to produce graph A. Identify the analyte and titrant that reacted to produce graph B. Diprotic acids contain two ionizable hydrogen atoms per molecule; ionization of such acids occurs in two steps. The first ionization always takes place to a greater extent than the second ionization. For example, sulfuric acid, a strong acid, ionizes as follows:This stepwise ionization process occurs for all polyprotic acids, or acids that contain more than one acidic hydrogen.When we make a solution of a weak diprotic acid, we get a solution that contains a mixture of acids.
