Plating

What affect does pH have on the plating process?

There is no simple answer. Some electroplating baths operate at high pH, so at low and some in the middle. Any deviation from their optimum will result in a loss of efficiency and even the bath not doing anything. Generally, if the pH is too low, you will start to codeposit hydrogen and for multifarious reasons, that is bad news. If the pH is too high, the cation (metal ion) could form hydroxides, which may or may not be soluble.

Using Multiparameter Meter at a Electroplating Plant

The most important parameters of the electrolytes used for electroplating ('plating bath' in technical parlance) include the pH. Depending on the nature of the plating method, the electrolytes can be acidic, basic or neutral. In case of this company, the pH value can vary between 1 and 13 pH, depending on the technology.
