WebA small amount of Na 2 CO 3 is added to the solution in order to bring the pH to about 9. The solution is standardized by taking a known amount of oxidizing agent, treating it with excess iodide ion and then titrating the liberated iodine with the solution to be standardized. WebDec 29, 2024 · I think to answer your question, the optimal pH for electroplating is more in relation to the availability of Sulfate ions than the excess of H+. This can be adjusted by adding additional H2SO4 to the electrolyte which will be an additional source of sulfate ions and also lower the pH.
