Consider the titration of a weak base (B- ) with a strong acid (HCl). Draw (this can be hand drawn) a pH (not pOH) vs mL HCl graph (it will not look the same as the one in question #13; if you start with a weak base, will the pH be low or high? As H+ is added, will the pH increase or decrease?). Label the titration curve with letters A-E, and describe the relative quantities of the dissociated base...

Ten Titration of Weak Acid with Strong Base A titration involves adding a reactant of known quantity to a solution of another reactant while monitoring the equilibrium concentrations. This allows one to determine the concentration of the second reactant. The equation for the reaction of a generic weak acid HA with a strong base is HA9(aq)+OH-(aq) -----> A-(aq)+H2O(l) A certain weak acid, HA, with a Ka value of 5.61x10-6, is titrated with NaOH Part A A solution is made by...
