Mol of vinegar
WebThe concentration of acetic acid, the analyte, in vinegar can be determined through an acid-base titration. CH,CO,H + NaOH + NaCH,CO2 + H2O At the equivalence point of a titration, the moles of acid added is exactly equal to the moles of base in the solution before the titration started. The equivalence point is achieved when sufficient titrant ... WebCalculations& Results Calculations and results pages are attached.
