ionogenn.

Brit.

/ʌɪˈɒnədʒ(ə)n/, U.S.

/aɪˈɑnədʒ(ə)n/,

/aɪˈɑnəˌdʒɛn/

Origin: Formed within English, by compounding; perhaps modelled on a German lexical item. Etymons: iono- comb. form, -gen comb. form.

Etymology: < iono- comb. form + -gen comb. form, perhaps after German Ionogen (1900 or earlier).

Physical Chemistry.

A compound which exists as ions when dissolved in a solvent; an electrolyte, esp. a weak electrolyte.

1901 A. Smith in Chem. News 6 Dec. 279/1 For materials which are salts in the wider sense, that is bodies which undergo ionisation, I have found the word ionogen very useful.

1922 H. W. Gruener Chem. xx. 188 When an ionogen like potassium chloride is dissolved in water, one of the electrons of the metal passes over to the nonmetal.

1978 P. W. Atkins Physical Chem. xxv. 823 The second class of electrolytes, the weak electrolytes (or the ionogens), show a marked dependence of their molar conductivity on the concentration.

1995 Synthetic Metals 72 164/1 The water content also enables the ionogen HCl to dissociate.

2002 G. M. Ballou Handbk. Sound Engineers (ed. 3) x. 220/2 The electrolyte commonly used in aluminum electrolytic capacitors is an ionogen which is dissolved in and reacts with glycol to form a paste-like mass.
