Abstract
A pH sensor-grid assembly is used in a submerged impinging jet cell to measure the interfacial pH during the reduction of dissolved oxygen in well controlled flow conditions. Experiments were performed in a 0.5m K2SO4 solution with and without carbonate ions. In each case a good agreement between experiment and theory is found. In particular it was confirmed that, in the absence of chemical reaction and for a totally mass transport controlled oxygen reduction reaction, stirring has no influence on the interfacial pH.
