I was currently put in the position to lead plate a copper strap under a 95%Pb 5%Sn MSA bath. I am not sure of the concentration of the chemicals all I know is it is composed of Solderon MHS, Solderon Pb concentrate, and Solderon Acid. I need to make more solution, if anyone might know the concentration of these chemicals please reply.

Thank you

When in doubt, read the instructions!? Try the supplier:

Also, searching turns up a few articles perhaps relevant:
'SolderOn Lead Analysis'
From another,
"We made up our 100-liter plating bath as follows: Solderon lead concentrate, 5% by volume; Solderon tin, 0.5%; Solderon acid 35%; MHS-L additive 5%; DI water 55%. The concentrates contain 450 g/l lead and 120 g/l tin, respectively, plus some additional acid."
-- it gives a 4 atom % tin deposit.

Note that the original supplier was LeaRonal which merged with Shipley and then Rohm & Haas.
