Miller,
It's been over 45 years since I last sat in a chemistry class but I do recall that metallic elements can be listed on an activity chart, from most to least active. Memory tells me that lead is a more active metal than tin, so I would assume that it would be attacked by the bluing salts more vigorously than tin would. Maybe someone younger than we old geezers, who has not been away from school so long, will chime in here.
After I posted this, I remembered that we live in the "Google' age, so I did a search and came up with the chart below. I was wrong, tin is MORE active than lead.





The metal activity series. Most active (most strongly reducing) metals appear on top, and least active metals appear on the bottom. displace H2 from water, steam, or acids

Li 2 Li(s) + 2 H2O() 2 LiOH(aq) + H2(g)
K 2 K(s) + 2 H2O() 2 KOH(aq) + H2(g)
Ca Ca(s) + 2 H2O() Ca(OH)2(s) + H2(g)
Na 2 Na(s) + 2 H2O() 2 NaOH(aq) + H2(g)
displace H2 from steam or acids
Mg Mg(s) + 2 H2O(g) Mg(OH)2(s) + H2(g)
Al 2 Al(s) + 6 H2O(g) 2 Al(OH)3(s) + 3 H2(g)
Mn Mn(s) + 2 H2O(g) Mn(OH)2(s) + H2(g)
Zn Zn(s) + 2 H2O(g) Zn(OH)2(s) + H2(g)
Fe Fe(s) + 2 H2O(g) Fe(OH)2(s) + H2(g)
displace H2 from acids only
Ni Ni(s) + 2 H+(aq) Ni2+(aq) + H2(g)
Sn Sn(s) + 2 H+(aq) Sn2+(aq) + H2(g)
Pb Pb(s) + 2 H+(aq) Pb2+(aq) + H2(g)
H2


For those who have forgotten their high school chemistry, reading from the top is : lithium, potassium, calcium, sodium, magnesium, aluminum, manganese, zinc, iron, nickle, tin, and lead.
