a strip of silver does not react with any of the solutions tested what must be true about silver

Question

the solutions are: lead acetate zince sulfate and copper sulfate

Answer 1

Obviously, silver must be less reactive than all of the other metals tested. OR In the activity series, silver must be below the other metals tested. What we are saying, (look back at my previous answer) that silver will not displace any ion above it in the activity series. Since it didn't displace anything, silver must be below all of those tested.
