An electrolyte solution, whose constituents are not electroactive in the range of applied potentials being studied, and whose ionic strength (and, therefore, contribution to the conductivity) is usually much larger than the concentration of an electroactive substance to be dissolved in it., elektrolüüdi lahus, mille komponendid ei ole rakendatud potentsiaalivahemikus elektriliselt aktiivsed ja mille ioontugevus on palju kõrgem kui elektriliselt aktiivsel komponendil
