A student is given four metals, E, G, Q and T. She carries out three tests. In each test, one metal is added to a solution of the sulfate of another metal. All the tests are carried out under the same conditions.
| Metal added | Solution | Observation |
|---|---|---|
| E | G sulfate | a coating of G forms on E |
| Q | G sulfate | no change |
| T | E sulfate | a coating of E forms on T |
The student wants to predict the result of a fourth test before doing it.
Which test would also produce a coating of metal?
T added to Q sulfate solution
Q added to E sulfate solution
G added to E sulfate solution
E added to T sulfate solution
