Web22 Apr 2024 · The bromothymol blue end point has a pH range of 6.0–7.6. Sulfuric acid is a diprotic acid, with a pK a2 of 1.99 (the first K a value is very large and the acid dissociation reaction goes to completion, which is why H 2 SO4 is a strong acid). The titration, therefore, proceeds to the second equivalence point and the titration reaction is WebAcetic anhydride - sulfuric acid (1:1) Molecular Formula CHOS. Average mass 200.167 Da.
