An unidentified metal, T, is a different element from iron, copper and silver.
The relevant part of the reactivity series is shown below.
| Most reactive | Least reactive | |
|---|---|---|
| iron | copper | silver |
Two tests are carried out using a solution of T sulfate.
| Test | Observation |
|---|---|
| iron added to T sulfate solution | a solid coating forms on the iron |
| copper added to T sulfate solution | no visible change |
Explain the position of T relative to iron and copper in the reactivity series.
Silver is added to a solution of T sulfate.
Predict whether a displacement reaction occurs.
Explain your prediction.
