Is my tin bath right?

I am doing a tin overplate for various parts, most of which are silver or copper underplated. My current bath is 10% sulfuric acid with stannous sulfate. First, is there a better bath available? Second, what is the best way to titrate? Thank you for your help.

Are you attempting to perform bright acid tin or matte acid tin plating? Are you using a proprietary process? If not you should be. Your process supplier should provide you with technical data for the operating parameters of the particular formulation you are (would be) using as well as analytical instructions for same.
