Ionization constants of weak acids
Web23.2 Acid and Base Ionization Constants. The relative strength of an acid or base is the extent to which it ionizes when dissolved in water. If the ionization reaction is essentially complete, the acid or base is termed strong; if relatively little ionization occurs, the acid or base is weak.As will be evident throughout the remainder of this chapter, there are many … Webacid, HCO, is an example of a weak diprotic acid. The first ionization of carbonic acid yields hydronium ions and bicarbonate ions in small amounts. The bicarbonate ion can also act as an acid. It ionizes and forms hydronium. ions and carbonate ions in even smaller quantities. is larger than . by a factor of 10, so HCO is the

An acid - A molecule that dissociates in water to yield H₃O⁺ - Is a proton DONOR (H⁺) - Accepts an electron pair to form a bond. A base - A molecule that dissociates in water to yield OH⁻ -Is a proton ACCEPTOR
WebWe can determine the relative acid strengths of NH 4 + and HCN by comparing their ionization constants. The ionization constant of HCN is given in Appendix I as 3.3 × 10 −10. The ionization constant of NH 4 + is not listed, but the ionization constant of its conjugate base, NH 3, is listed as 1.8 × 10 −5. WebIonization of a Diprotic Acid “Carbonated water” contains a palatable amount of dissolved carbon dioxide. The solution is acidic because CO reacts with water to form carbonic acid, HCO. What are and in a saturated solution of CO with an initial [HCO] = 0.033 M? Solution As indicated by the ionization constants, HCO is a much stronger acid than
