Ethylammonium nitrate (EAN) is a protic room-temperature ionic liquid and classified into an amphoteric solvent. The equilibrium constant K-S = [EtNH2][HNO3] has directly been obtained for the first time by using an ion-selective field effect transistor (ISFET) electrode. The obtained K-S value is of 10(-10.0) mol(2) dm(-6), indicating that the neutral EAN involves HNO3 and EtNH2 molecules as much as 1.0 x 10(-5) mol dm(-3), or the pH (= - log[HNO3]) is 5 at 298 K.
