WebOct 12, 2024 · The NaOH solution is standardized using the titration of a primary standard of KHP (Figure 2). The titration reaction of KHP with NaOH is as follows: C 8 H 5 KO 4 ( aq) + NaOH ( aq) → H 2 O + C 8 H 4 NaKO 4 ( aq) The NaOH solution is prepared by measuring out about 25 g of NaOH (s), which is then transferred to a 1 L volumetric flask. WebThe calculated factor is then used as the correction factor to the titrant. The measured value of the titer is multiplied with the nominal concentration. Titer = c (x) / c~ (X) c = c~ (x) × …
