Help please, @.Sam. Thanks!
What do you know about redox reactions?
Cd is more easily oxidized than Pt
I think the Pt is plating the Cd, right?
Which means that the Pt is going from a cation to metal thus it is being reduced.
Yes when Pt is reduced then it is the oxidising agent
Sweet, and Cd is the reducing agent, right?
And cadmium went from 0 to 2+, which is oxidised
Awesome, thanks so much!
