Hydronium - Wikipedia

Determination of pH. The concentration of hydronium ions determines a solution's concentration of hydroxide ions determines a solution's molecules in pure water auto-dissociate ( react with each other) into hydronium and hydroxide ions in the following equilibrium: . 2 H 2 O ⇌ OH − + H 3 O +. In pure water, there is an equal number of hydroxide and hydronium ions, so it is a neutral solution.

Volatiles have a high vapour pressure so, if they are incorporated into solid or liquid material during their transport outwards, they will have a tendency to escape, atom by atom, from their host compounds thereby increasing the local gas pressure: at near-surface levels, the gases contributing to the enhanced pressure may include methane and other alkanes, carbon dioxide, carbon monoxide, hydrogen …

Clathrate hydrates in interstellar environment

completely new IR peak (3,017 cm−1) appears alongside the peak at 3,009 cm−1 after 25 h of annealing at 30 K. This new peak (3,017 cm−1) is attributed to the CH 4 hydrate, where CH 4 is trapped in the CH cage. The rest of the untrapped CH 4 remained in the pores of amorphous ice. The experimental blue shift of 8 cm−1 is due to the entrapment of CH 4 in the hydrate cage. Here, the trapped CH 4 inside …
