Hi Eric, Thanks for the input. Since the only reference I found for LiPd was on the B&S website, that is where the numbers come from. This seems to be the numbers they use for the product they sale. Because you can never have enough reference's for mixing up chemistry, what reference do you have or is there another place you could point me to online? Agree that the 1.7 to 2.3 is quite different from the NaCl or NH4Cl.
