CHM 132 Lecture Notes - Lecture 9: Electroplating, Mecha, Galvanic Cell
Document Summary
Chem all abt where do electrons want to be we can change this by applying voltage e. Zn s is an ode electrode where oxidation occurs lose electrons. Reducing agents oxidation are reduced cause reduction are oxidized. Stops when equilibrium reached cor electrode all used up. Atom to which e attracted based on electro negativity. Have tables w potentials listed for each half rim. Zn s half reaction compare to standard normal hydrogen electrode. 2h12 n"t ci m 11nhe t 2 ht. Positive voltage wants to give up electrons reduction potentials in table favorable half reaction rims electron in these. Sto ich current of electrode can run inherent electrons 1mi n tells us related to degradation how long battery. Iaraday"s constant f charge of 1 mo l of e. If i draw 1 ampere mots and g of cathode and a node used up. How much to produce 1kg all min in our factory current will we need.
