WebThe four stages of a titration: Initial state (added titrant volume = 0 mL): pH is determined by the acid being titrated; because the two acid samples are equally concentrated, the weak acid will exhibit a greater initial pH. Pre-equivalence point (0 mL < V < 25 mL): solution pH increases gradually and the acid is consumed by reaction with ... WebCalculating pH for Titration Solutions: Strong Acid/Strong Base A titration is carried out for 25.00 mL of 0.100 M HCl (strong acid) with 0.100 M of a strong base NaOH (the titration curve is shown in Figure 14.18).
