Analyzing for Fluoboric Acid in Tin Plating Solution




I am attempting to set up a tin plating process and need a procedure for determining the concentration of fluoroboric acid in the plating solution. If you know of any such procedures, please let me know.

Check out page 552 of the 98 Metal Finishing Guidebook. They have the test methods listed for all the acids there.

You can either check with your Fluoborate vendor/manufacturer or in the Metal Finishing Guidebook.

This analysis will give you an Empirical (EMP) reading, and usually is only a titration with a Standard Solution of Sodium Hydroxide to a turbid endpoint. Multiply by an appropriate factor and you have the concentration.
