sulfuric acid for pH down? Thread starter poutineeh; Start date Aug 27, 2008; P. poutineeh Well-Known Member. Aug 27, 2008 #1 i dont have a hydro shop around me. so i went to a pet store, and the only thing they had for pH down was sulfuric acid. is this safe for plants, assuming i do the correct dosages pH is a measurement of the amount of H+ (acidic hydrogen) in water. Sulfuric acid is a strong acid. That means the at least one of the hydrogens will dissassociate from the sulfuric acid. Then the pKa (equilibrium constant for acid dissassociation) comes into effect. Acetic acid is a weak acid Pure sulfuric acid has a specific gravity of 1.830 at 25 °C (77 °F); it freezes at 10.37 °C (50.7 °F). When heated, the pure acid partially decomposes into water and sulfur trioxide; the latter escapes as a vapour until the concentration of the acid falls to 98.3 percent The tiny water droplets containing sulfuric acid provide a ready surface to attract more molecules of water to form a larger droplet of dilute sulfuric acid. Water droplets collected from the base of clouds in the Eastern U.S.during the summer have an average pH of 3.6, with some values as low as pH 2.6 Other superacids include the carborane superacids [e.g., H(CHB 11 Cl 11)] and fluorosulfuric acid (HFSO 3). The carborane superacids may be considered the world's strongest solo acid, as fluoroantimonic acid is actually a mixture of hydrofluoric acid and antimony pentafluoride. Carborane has a pH value of -18
