definition
A negatively charged ion.
Examples of anions in a Sentence
When the solutions may be taken as effectively dilute, so that the gas laws apply to the osmotic pressure, this relation reduces to E _ nrRT to c1 ey gE c2 where n is the number of ions given by one molecule of the salt, r the transport ratio of the anion, R the gas constant, T the absolute temperature, y the total valency of the anions obtained from one molecule, and c i and c 2 the concentrations of the two solutions.
This "passivity" may be brought about by immersion in other solutions, especially by those containing such oxidizing anions as NO' 3, C10' 3, less strongly by the anions SO" 4, CN', CNS', C2H30'2, OH', while Cl', Br' practically inhibit passivity; H' is the only cation which has any effect, and this tends to exclude passivity.
Mixed metal oxides and phases containing mixed anions, such as oxide fluorides, provide our current focus.
Retention of organic anions causes a progressive increase in the anion gap and a further fall in plasma bicarbonate concentration.
A recent review has indicated that sulfate salts tend to have lower penetration rates than other common anions.
Thermal instability of the compounds with large anions is a function of the polarizing power of the cation.
We have shown that fluoride anions can be used to generate helical structures in the solid state.
What we get is a solution which contains sodium cations (positive ions) and chloride anions (negative ions ).
This leads to the production of radical molecular cations and anions of large biomolecules.
The zone is weakly hydrogen-bonded, fluid and reactive, and accumulates small cations, multivalent anions and hydrophobic solutes.
A sodium cation will therefore be able to attract chlorine anions in all directions, and vice-versa.
The greatest effect is due to the most strongly hydrated anions.
These holes could be used to coordinate cations or anions, just like organic macrocyclic ligands.
By adding an extra pyrrole group we have enhanced the affinity of this class of receptor for anions.
The cations are arranged into a face centered cubic structure with the anions occupying the tetrahedral sites.
If some of the anions, instead of being simple iodine ions represented chemically by the symbol I, are complex structures formed by the union of iodine with unaltered cadmium iodide - structures represented by some such chemical formula as I(CdI 2), the concentration of the solution round the anode would be increased by the passage of an electric current, and the phenomena observed would be explained.
