1. A student is given five metals, labelled A, B, C, D, and E. The student is also given 1.0 mol/L solutions of the nitrates of the metal ions: A,

B, C", D, and E2. The student records the following experimental data: Metal A remains unchanged in all solutionsMetal C becomes coated with another metal when placed in solutions with A, B, D, or E• Metal D becomes coated with another metal when placed in solutions with A or B2 Based on the experimental data, what is the order of the metals in increasing strength as reducing agents? Explain your answer.
