Determination of Boric Acid in Ni baths

Boric acid (H₃BO₃) is a crucial component in nickel plating baths as it can directly influence the quality of the nickel coating obtained. It is critical for its buffering ability to regulate pH, prevent the formation of undesirable compounds such as nickel hydroxide, improve the luster of the coating, reduce internal stresses, and promote uniform deposition. Typically, the concentration of boric acid that enables the effective performance of its functions is between 30 and 45 g/L. Quantitative determination of this parameter enables the electrodeposition process to be carried out efficiently and with reliable results.
