Complete the following equation: at 25 o C, K a  x K b  = K w A weak acid titrated with a strong base leads to a pH > 7 at the equivalent point. In a buffer solution how are the pH and the pKa value related? pH=pKa+log(base/acid) Circle which is amphoteric H 2 0 Circle effective buffer systems: NaF/HF and NaH 2 PO 4 /Na 2 HPO 4 List the following molecules in order of increasing acid strength NaOH<H 2 0<HCO 2 H<HCl How are the pH and the pOH value related? pH+pOH=14 An initial pH of 1.0, an equivalence point at pH=7 and a relatively long, nearly vertical middle section  correspond to a titration curve for a strong acid titrated by a strong base Addition of Na 2 SO 4  to sparingly soluble BaSO 4  in water will decrease the Ba 2+  ion concentration in the  aqueous solution The effect of a catalyst on a chemical equilibrium composition is to increase the rate at which  equilibrium is achieved Write the equilibrium constant expressions for the following reactions in terms of concentrations PbCl 2 (s)   Pb 2+ (aq) + 2Cl -  (aq);;;;;;;K
