The salt hydrolyzes readily: [Me 3 O] + [BF 4] − + H 2 O → Me 2 O + MeOH + H + [BF 4] −. Trimethyloxonium tetrafluoroborate is generally ranked as the strongest commercially available reagent for electrophilic methylation, [1] being stronger than methyl sulfonate esters, including methyl triflate and methyl fluorosulfonate ("magic methyl ...
Lithium perchlorate is also used as an electrolyte salt in lithium-ion batteries.Lithium perchlorate is chosen over alternative salts such as lithium hexafluorophosphate or lithium tetrafluoroborate when its superior electrical impedance, conductivity, hygroscopicity, and anodic stability properties are of importance to the specific application.

Roussin's red salt is the inorganic compound with the formula K 2 [Fe 2 S 2 (NO) 4]. This metal nitrosyl was first described by Zacharie Roussin in 1858, making it one of the first synthetic iron-sulfur clusters .
A chemistry professor explains the science that makes salt a cheap and efficient way to lower freezing temperature.
Sodium ethyl xanthate is a pale yellow powder. Its aqueous solutions are stable at high pH if not heated. It rapidly hydrolyses at pH less than 9 at 25 °C. It is the conjugate base of the ethyl xanthic acid, a strong acid with pK a of 1.6 and pK b estimated as 12.4 for the conjugate base. [6]
With just one game down in Week 15, one NFL team's clinching scenario is already off the table. A tie between the Los Angeles Rams and San Francisco 49ers on Thursday night would have kept alive ...
Authorities have identified the woman who burned to death after she was set on fire inside a New York City subway train as 57-year-old Debrina Kawam.
The trimethyloxonium salt is available from dimethyl ether via an analogous route. [6] These salts do not have long shelf-lives at room temperature. They degrade by hydrolysis: [Et 3 O] + [BF 4] − + H 2 O → Et 2 O + EtOH + H + [BF 4] −. The propensity of trialkyloxonium salts for alkyl-exchange can be advantageous.
