WebApr 11, 2024 · Similarly, the titration of the base (strong or weak) was performed by adding an aliquot of the titrant mixture containing 0.1 mol L −1 HCl and 1% (m/v) phenolphthalein (for strong base) or 1% (m/v) methyl red (for weak base) through the channel. Then, the devices were allowed to dry at room temperature (23±1 °C) for 5 minutes. http://www.columbia.edu/itc/chemistry/chem-c2407/hw/acid-base2002.pdf

Therefore, with the pH at 12.5 mL being 4.76, the pK a is 4.76, making the K a = 10-4.76 = 1.74*10-5. d) Thymol blue is the best indicator for signaling the endpoint of the titration because the pH … cordless person winch

Then it was titrated with the strong acid or strong base respectively while measuring the pH of the buffer (using a pH probe) on addition of every 1 ml of acid or base from the burette. WebWeak Acid Titration The weak-acid solution has a higher initial pH. The pH rises more rapidly at the start, but less rapidly near the end point. The pH at the equivalence point does not equal 7.00 (pH > 7.00) for the weak acid titration. PURPOSE To construct 2 titration curves.
