La chimie des solutions : englobe un grand nombre de thèmes dont l’intérêt est le plus souvent le dosage d’un composé en milieu liquide On s'intéressera dans le cadre de ce cours uniquement aux solutions aqueuses Les méthodes classiques de dosages employées dans cette branche de la chimie sont la pH-métrie, l'oxydoreduction et la conductimétrie, thèmes fréquemment posés à l'occasion des épreuves de concours ou de baccalauréat

Ces techniques de dosage ont l'avantage d'être faciles et rapides à mettre en oeuv Le matériel nécessaire à leur réalisation étant d'un point de vu économique abordable Outre l'aspect pédagogique, elles sont couramment employées dans l'industrie pour des contrôles de routine tel que la vérification de la concentration d'un bain de traitement de surface
