Hydronium
The Eigen solvation structure has the hydronium ion at the center of an complex in which the hydronium is strongly hydrogen-bonded to three neighbouring Solid hydronium salts
For many strong acids, it is possible to form crystals of their hydronium salt that are relatively stable.

Hydronium perchlorate
Hydronium perchlorate is the chemical compound with the formula . It is an unusual salt due to it being a solid and stable hydronium salt. Production
Hydronium perchlorate is produced by the reaction of anhydrous perchloric acid and water in a 1:1 molar ratio:

Hydrogen Ions — Common, right? The Wikipedia entry for Ion states "A positively charged hydrogen ion (or proton) can readily combine with other particles and therefore is only seen isolated when it is in a gaseous sta...
This is not a paradox because in aqueous solutions, hydrogen ions exist as $H_3O^+$, also known as hydronium or hydroxonium.

Is pH found using negative log because the scientific notation of the number of hydrogen atoms in a solution is always negative? I understand subtraction negates addition, and since log and exponents are basically add...
Under reasonable conditions, at any given moment, only a tiny fraction of water molecules are dissociated into the ${\rm H}^+$ and ${\rm OH}^{-}$ ions. Therefore, the molar concentrations of these ions are very small numbers, so their logarithms are negative. The customary definition of pH takes thi...

水合氢离子
水合氢离子(英语:Hydronium),也称离子、或氧𬭩(英语:Oxonium),指的是氢正离子与水分子配位结合而生成的正离子。与水结合之氢正离子,通常的来源为可溶于水的酸,可溶于水的酸溶在水中会解离成为酸根离子与氢离子,由于水分子能提供孤对电子,所以氢离子便与水分子配位结合而生成水合氢离子。

What is the pH of the mitochondrial intermembrane space? The proton gradient is stored between the mitochondrial double membrane. More protons mean more hydronium ions and lower pH, but how much exactly?
I agree with @alina that it is well accepted that the pH difference across the inner membrane is ~0.5-1 units. However, the absolute value of the pH in the IMS will vary between organisms and even cells. It is experimentally difficult to measure it, therefore most of the times only the matrix pH has...

Sodium trifluoroacetate
cations to form trifluoroacetic acid:
CF3CO2- + H3O+ <=>> CF3CO2H + H2O
The general reaction with hydronium is in equilibrium due to the similarity in pKa between trifluoroacetic acid and the hydronium ion.
