Summary
Researchers synthesized a new noble gas compound, [XeCl]+[Sb2F11]-, a stable orange salt. This discovery nears the theoretical limit for noble gas halogens, making similar compounds unlikely to be synthesized.
Area of Science:
- Inorganic Chemistry
- Noble Gas Chemistry
Background:
- Noble gas compounds are rare and challenging to synthesize.
- Previous research focused on lighter noble gases and different halogenations.
Purpose of the Study:
- To explore chlorine-fluorine exchange reactions in noble gas cations.
- To synthesize and characterize new noble gas halogen compounds.
Main Methods:
- Chemical synthesis involving chlorine-fluorine exchange in XeF+.
- Characterization of the resulting crystalline salt, [XeCl]+[Sb2F11]-.
Main Results:
- Successful synthesis of the orange crystalline salt [XeCl]+[Sb2F11]-.
- The compound is stable below -10°C.
- The number of known noble gas monohalogen cations increases to three.
Conclusions:
- The synthesis of [XeCl]+[Sb2F11]- approaches the theoretical limit for noble gas monohalogen cations.
- Further synthesis of similar compounds, except possibly ArF+, appears unlikely.

03:24Common Ion Effect
47.0K
Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Châtelier’s principle. Consider the dissolution of silver iodide:

The movement of ions like sodium, potassium, and calcium into and out of the cell is essential to maintain the electrochemical gradient in living cells. The ion channels—a class of membrane transport proteins—help maintain this ionic gradient for the smooth functioning of physiological activities such as maintaining cell size and volume, conducting nerve impulses, and gas and nutrient exchange.

03:45Formation of Complex Ions
26.2K
A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...

79.3K
In ordinary chemical reactions, the nucleus — which contains the protons and neutrons of each atom and thus identifies the element — remains unchanged. Electrons, however, can be added to atoms by transfer from other atoms, lost by transfer to other atoms, or shared with other atoms. The transfer and sharing of electrons among atoms govern the chemistry of the elements. During the formation of some compounds, atoms gain or lose electrons to form electrically charged particles called...

Salts with Acidic Ions
Salts are ionic compounds composed of cations and anions, either of which may be capable of undergoing an acid or base ionization reaction with water. Aqueous salt solutions, therefore, may be acidic, basic, or neutral, depending on the relative acid-base strengths of the salt’s constituent ions. For example, dissolving the ammonium chloride in water results in its dissociation, as described by the equation:
