Experiment 18 Prelaboratory Assignment Potentiometric Analyses Date Desk No I. a. For a weak acid (e.g. CH COOH) that is titrated with a strong bave teg. NaOH), what species (ions/molecules) are present in the solution at the stoichiometric point? b. For a weak acid (e.g. CH COOH) that is titrated with a strong base (e.g.. NaOH), what species.
Here's how to approach this question. Calculate the moles of NaOH dispensed at the stoichiometric point by multiplying the molar concentration of NaOH ( 0.15 m o l L) by its volume ( 0.165 L ). So, 4. Final NaOH = 16.8mL 5. NaOH from graph = 16.5mL ( at the equilvalence point) 7. ….
