In electrochemistry, ITIES is an acronym for the "Interface between Two Immiscible Electrolyte Solutions". Usually, one electrolyte is an aqueous electrolyte composed of hydrophilic ions such as NaCl dissolved in water and the other electrolyte is a lipophilic salt such as tetrabutylammonium tetraphenylborate dissolved in an organic solvent immiscible with water such as nitrobenzene, or 1,2-dichloroethane. An ITIES is an electrochemical interface that is either polarisable or polarised. An ITIES is said ''polarisable'' if one can change the Galvani potential difference, or in other words the difference of inner potentials between the two adjacent phases, without noticeably changing the chemical composition of the respective phases (i.e. without noticeable electrochemical reactions taking place at the interface). An ITIES system is said ''polarised'' if the distribution of the different charges and redox species between the two phases determines the Galvani potential difference. ==Charge transfer reactions at ITIES== Three major classes of charge transfer reactions can be studied at ITIES: *Ion transfer reactions. *Assisted ion transfer reactions. *Heterogeneous electron transfer reactions. The Nernst equation for an ion transfer reaction reads :, where is the standard transfer potential defined as the Gibbs energy of transfer expressed in a voltage scale. : The Nernst equation for a single heterogeneous electron transfer reaction reads :, where is the standard redox potential for the interfacial transfer of electrons defined as the difference the standard redox potentials of the two redox couples but referred to the aqueous Standard Hydrogen Electrode (SHE). : 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「ITIES」の詳細全文を読む スポンサード リンク
