Acidity however, arises from various other factors. To quote an answer I had given way back: Now, what makes an acid strong? read more
Sulfate has a lot of electronegative atoms in it. Because of this, the hydrogens in sulfuric acid have a lot of ionic characteristic. And just like most other ions, it dissociates in water. Acidity is measured by concentration of hydrogen ions in solution. It is the negative log of this concentration that gives pH. read more
Sulfuric acid aerosol toxicity is dependent on the hydrogen ion content of the aerosol. One mechanism by which sulfuric acid may produce its toxicity is by changing extracellular and intracellular pH. read more
