Overtitration
Web(c) Titrant volume = 25.00 mL. This titrant addition involves a stoichiometric amount of base (the equivalence point), and so only products of the neutralization reaction are in solution (water and NaCl).Neither the cation nor the anion of this salt undergo acid-base ionization; the only process generating hydronium ions is the autoprotolysis of water. WebExcess titrant causes a color change to blue and shows overtitration. 5. The final result marks the arithmetic mean of two determinations differing by no more than 5% as a result of the less amount. 6. Save the result in the score sheet.
