Unformatted text preview: the acid from this step. Calculations: Standardization: KHP is a monoprotic acid, so the reaction can be simplified as KHP (aq) + NaOH (aq) & KNaP (aq) + H 2 O (l) Using standard stoichiometric techniques, calculate the molarity of NaOH for each run. Take the average and determine the standard deviation. Concentration of the Acetic Acid: The acid is monoprotic, so again, we can write HA (aq) + NaOH (aq) & NaA (aq) + H 2 O (l) Use standard stoichiometric techniques to calculate the moles of acid for each run. Don’t forget to take the dilution into account; once you calculate the concentration of acetic acid in the diluted solution, multiply by four to get the concentration of the original vinegar. Convert the concentration from molarity to % w/v in the standard method. Take the average and determine the standard deviation....
