Question
A titration involves adding a reactant of known quantity to a
solution of an 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
HA(aq) + OH(aq) →A¯(aq) + H₂O (1)
A certain weak acid, HA, with a K, value of 5.61 x 10 ", is titrated with NaOH.
