Webb13 apr. 2024 · TMT is based on dilution factor to quantify the relative proportions of titrant and sample through a chemical tracer (colorimetric indicator) in the titrant. The dilution factors are used in the equivalence point calculation in place of physically metered volume, masses, flow rates, or peak width (time). WebbTitration analysis Statistically, we find fewer ethanoate anions than trichloroethanoate anions in the respective solutions of the two acids. And if there are fewer ethanoate anions in solution per mole of ethanoic acid, then there will be fewer solvated protons.In other words, the extent to which ethanoic acid dissociates is less than the corresponding …
