SUMMARY
The discussion focuses on calculating the molarity of sodium hydroxide (NaOH) used in a titration with cyclohexylaminoethanesulfonic acid. Given that 22.63 mL of NaOH was added to 1.226 g of the acid dissolved in 41.37 mL of water, and the resulting pH was measured at 9.24, participants emphasized the importance of determining the pKa value from a reference table to facilitate the calculation. The molarity of NaOH can be derived using the formula M = moles of solute/volume of solution in liters.
