Based on experiments conducted:
1. State an inference based on the observations in Experiment I.
2. State the name of the ion that gives blue colour to the solution and the shiny grey solid formed in
Experiment III.
3. Compare the strength of electropositivity of metal P and metal T based on Experiment II.
4. Compare the strength of electropositivity of metal T and metal W based on Experiment III.
5. Arrange metals P, T and W in ascending order of electropositivity in the electrochemical series.
