I can help you solve mathematical equations quickly and easily. Keep reading and find out! Step 2: To accurately draw our titration curve, we need to calculate a data point between the starting point and the equivalence point. Strong acids and strong bases completely dissociate, so the reaction yields a solution with a neutral pH (pH = 7). Calculating the Post Volume. In contrast, neutralization involving a weak acid and/or a weak base requires that you know and use the dissociation constant. For example. \(NaOH + H_2SO_4 \leftrightharpoons H_2O + NaSO_4\). ): 0.5 moles NaOH x 1 mole H 2 SO 4 /2 moles NaOH = 0.25 moles H 2 SO 4 needed Finally, calculate the volume of H 2 SO 4 needed to provide 0.25 moles H 2 SO 4: Set up an ICE table to find the concentration of H3O+: \[K_a=(7)(10^{-3})=\dfrac{(x^2)M}{(0.1-x)M}\], \[pH=-\log_{10}[H_3O^+]=-\log_{10}(0.023)=1.64\].
