Jeggys Posted February 17, 2021 Posted February 17, 2021 Bonjour je ne comprend pas comment faire pour calculer le pH ici Merci d'avance! Apparemment Ph=pka mais pourquoi ? Quote
Ancien Responsable Matière Solution SeverusRogue Posted February 17, 2021 Ancien Responsable Matière Solution Posted February 17, 2021 Bonsoir @Jeggys ! pH = pKa quand tu as autant d'acide que de sel basique (ici 0,45 mol de chaque) Quote
