TECH Brief 8 – Modelling MoU H2SO4 Determination


A modelling approach is used to estimate the measurement of uncertainty expressed as an expanded uncertainty for the molarity of sulphuric acid as determined by titration with standard sodium carbonate. Each uncertainty is identified, quantified, and combined. The largest contributor to the measurement uncertainty is that of repeatability in the determination followed by the volume of sulphuric acid and sodium carbonate.
