a positively charged ion. Compare anion.

cation

A positively-charged ion–eg, Na+, K+, Ca2+, Mg2+

cat·i·on

(kat'ī-on)
An ion carrying a charge of positive electricity, therefore going to the negatively charged cathode.
[G. katiōn, going down]

cation

A positively charged atom, such as Na+ or K+, which is attracted towards a negative electrode (cathode). An atom which, in solution, takes a positive charge. Unlike charges attract; like charges repel.

Cation

An ion carrying a positive charge due to a loss of electrons. Cations in the body include sodium, potassium, magnesium, and calcium ions.

cation

positively charged ion, attracted to a negatively charged cathode

cation (katˑ·īˈ·n),

n a positively charged atomic or molecular species. See also ion.

cation

a positively charged ion.

cation-anion balance
the balance in serum or plasma between the anions and cations must equilibrate near to the level of 155 mEq/l. Estimation of any imbalance, usually by chloride and bicarbonate measurement, is basic to any determination of acid-base abnormality.
cation channels
channels through selectively permeable membranes via which only cations can migrate.
dietary cation-anion difference
prepartum has a major influence on the incidence of hypocalcemia (milk fever) in dairy cattle and, in the control of the disease, is manipulated so as to result in a metabolic acidosis which facilitates the mobilization of calcium. Defined as milliequivalents of (Na+K)-(Cl+S) per kg DM diet.
cation-exchange resin
ion-exchange resin.

Key statement: A process for providing interaction between particulate filler and a functionalized polymer involves a composition that includes at least three components: (1) a polymer that includes a functional group including an acidic cation of a primary or secondary amine functionality, (2) a material including a functionality capable of reacting with the acidic cation, and (3) particulate filler.
Cation exchange reactions in soils have been paid considerable attention in soil science, and previous experimental and modelling studies indicate a good understanding of the processes.
