Anion's lyre and the dolphin were translated to the stars.
On Tarentine coins a man and dolphin appear, and hence it may be thought that the monument at Taenarum represented Taras and not Anion.
If an atom gains an it is called an anion.
Acid dye These molecules are generally sodium salts which dissociate to form the acid dye anion.
Retention of organic anions causes a progressive increase in the anion gap and a further fall in plasma bicarbonate concentration.
This produces an electron which adds to the benzene ring to generate a radical anion.
The superoxide anion radical can also result in the formation of the dangerous hydroxyl radical.

Dr. Andrew L. Hector Research interests - nitride materials Materials with nitride materials Materials with nitride as the anion are much less well studied than those with oxide.
If the anode consist of platinum, cyanogen gas is evolved thereat from the anion Ag(CN) 2, and the platinum becomes covered with the insoluble silver cyanide, AgCN, which soon stops the current.
It is usual to express the results in terms of what is called the migration constant of the anion, that is, the ratio of the amount of salt lost by the anode vessel to the whole amount lost by both vessels.
Immediately on his arrival Anion related his story to Periander, who was at first incredulous, but eventually learned the truth by a stratagem.
The Romans are credited with having purposely introduced the edible snail (Helix pomatia) into England, and the common garden snail and slugs (Helix aspersa, Limax agrestis and Anion hortensis) have been unwittingly established in New Zealand.
But if one ion, say the anion, travels faster through the liquid than the other, the end of the solution from which it comes will be more exhausted of salt than the end towards which it goes.
If we assume that no other cause is at work, it is easy to prove that, with non-dissolvable electrodes, the ratio of salt lost at the anode to the salt lost at the cathode must be equal to the ratio of the velocity of the cation to the velocity of the anion.
Periander further appears as a patron of literature, for it was by his invitation that the poet Anion came to Corinth to organize the dithyramb.
The original volumes have each an engraving of Anion and the Dolphin, and the appropriate inscription in usum serenissimi Delphini.
On the theory that the phenomena are wholly due to unequal ionic velocities this result would mean that the cation like the anion moved against the conventional direction of the current.
As we have seen above, when a solution is placed in contact with water the water will take a positive or negative potential with regard to the solution, according as the cation or anion has the greater specific velocity, and therefore the greater initial rate of diffusion.
According to Herodotus, Anion being desirous of exhibiting his skill in foreign countries left Corinth, and travelled through Sicily and parts of Italy, where he gained great fame and amassed a large sum of money.
They affirmed that he had remained behind at Tarentum; upon which they were suddenly confronted by Anion himself, arrayed in the same garments in which he had leapt overboard.

Here the ions are potassium and the group Ag(CN)2.1 Each potassium ion as it reaches the cathode precipitates silver by reacting with the solution in accordance with the chemical equation K--+KAg(CN) 2 =2KCN+Ag, while the anion Ag(CN) 2 dissolves an atom of silver from the anode, and re-forms the complex cyanide KAg(CN) 2 by combining with the 2KCN produced in the reaction described in the equation.
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.
Anion chose the latter, and as a last favour begged permission to sing a parting song.
