The Bronsted-Lowry Model of acidity is often used to classify a substance as an acid or a base. The central ion that is tracked in the Bronsted-Lowry Model is the hydrogen ion. Hydrogen ions (also known as protons) are transferred from a Bronsted-Lowry acid to a Bronsted-Lowry base. ...

In this new metal-free oxidation system (Na2S2O4/TBHP), SO4.– can be used as a controllable oxidant to oxidize various aromatic alcohols to the corresponding aldehydes in good yields without any acid formation at room temperature. SO4.– was determined by a DMPO (5,5-dimethyl-1-pyrroline-N...
The K2HPO4(aq) stock solution was prepared from anhydrous K2HPO4(s), and the molality standardization procedure (in triplicate) by conversion to Mg2P2O7(s) has been described previously [11]. The reference KCl(aq) stock solution was prepared from KCl(s) and The acid and base equilibria...

However, binary nucleation of H2SO4–H2O is slow and, so, ternary or multicomponent nucleation with extra vapours such as ammonia (NH3)9 and organics10,11 is necessary to account for observed new-particle-formation rates3,8,12. Ammonia stabilizes acid–base nucleation and strongly enhances ...
