NiI2 Examples – State whether each will be acidic, basic, or neutral in aqueous solution: 1. DISSOCIATION CONSTANTS OF INORGANIC ACIDS AND BASES The data in this table are presented as values of pK a, defined as the negative logarithm of the acid dissociation constant K a for the reaction BH B– + H+ Thus pK a = –log K a, and the hydrogen ion concentration [H+] can be calculated from Ka H B BH = [ ] + −. If the formation of the products releases more energy than it took to break the bonds in the reactants, the reaction must give off some of this energy as heat, and so is exothermic. If it completely separates into ions so that practically none of the molecular form remains, it is called a strong electrolyte. Three different methods of calculation using five independent data sets lead to accurate values of the dissociation constant; these are in excellent agreement with each other. The chemical equations for the reactions are shown below. In these solutions, the hydrogen ion concentration was known , and A could be computed by means of equation 3.

Most questions answered within 4 hours. In the reaction NH3 (aq) + H2O (l) --> NH4+ (aq) + OH- (aq), NH3 is the weak base, but does that mean that H2O is considered an acid because it donates its proton to form OH-? Remember water can act as an acid or a base. 0 mL of water at 27. The balancer is case sensitive. Sevian Hydrolysis example problem similar to a text book exercise, Ex. (a) The titration is a 1:1 reaction between a weak acid and a strong base. Sodium chloride (NaCl) is easily water soluble, which means the ions will dissociate from each other. It is generally more convenient to report intensive properties, thus the heat capacity of a substance is usually reported as a specific heat capacity. pK a; sulfuric acid. Sodium hydroxide is a strong base and strong electrolyte. ) 2 Fe(s) + 3 S(l) Fe 2 S 3 (s) d. Hot packs and cold packs (see Figure below ) use this property.
