WebSince mmol = Mx mL, it can be said that, at the end point of the titration, (mL NaOH added ) (M NaOH) = (25.00 mL HCl) (0.100 M HCl) [3.2] Part B: By substituting the average value of the molarity of NaOH ( Part A) and its end point volume into equation [3.2], we can calculate the molarity of the unknown acid from the relationship mL NaOH added ... 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). Calculate the pH at these volumes of added base solution: (a) 0.00 mL (b) 12.50 mL (c) 25.00 mL (d) 37.50 mL. Solution

WebDec 30, 2024 · To work out an unknown concentration of 0.15 mL HCl: Use the 1:1 ratio formula because one mole of HCl reacts with one mole of NaOH – HCl + NaOH → NaCl + H2O. Multiply the molarity of the strong base NaOH by the volume of the NaOH ( MB × VB = 0.500 M × 20.70 mL ). WebThe potentiometric titration was conducted once at each level. Calibration curve was drawn by plotting test sample weight in gram on x axis and titre values on y axis. The values of correlation coefficient, slope and intercept are given in table 3.
