WebSep 1, 2000 · The pH change is caused by the poor efficiency of your anodes. You don’t say if you are using any insoluble anodes in the strike bath, but if you are, they have low efficiency compared to soluble anodes. This will cause hydroxide ions to be generated at the anode surface, which in turn will increase the pH of the bath. If your copper anodes ...
