Document Summary

Pain is a result of electrical simulaion caused by a current between aluminum foil and the metal in your teeth (illing amalgam). Amalgam is made of mercury and other alloys: silver, tin, copper, and zinc. These act as the anode or cathode in a galvanic cell. Aluminum anode: find the oxidaion reacion for the anode. In the illing, ind out what metal is the most easily oxidized and write a reacion for it. Electroplaing uses the electrodes -> they paricipate in the reacion. Ni (s) ni2+ + 2e- eox= +0. 28. 1 mole of an electron will plate out 1 mole of na metal. 2 moles of electrons will plate out 2 moles of na metal. Al3+ + 3e- al 3:1 (here you need 3 moles of al to get 1 mole of al) A coulomb is the quanity of charge passing a point in 1 second (1 amp)
