[NewCandle] Measuring Half-Cell Charge

[Frederick Sparber]

First of all Keith, Copper Carbonate Hydroxide "Malachite" Cu2CO3(OH)2 is green.

Hence the green patina on the Statue of Liberty.

Patricia Thiel says there could be 10^15 water molecules per square cm
on a metal-water interface. If a major portion of these donate an
electron to the high work function "electron hungry" metal the
negative charge could go as high as
10^-4 coulombs per cm^2.  Likely much less,however.

It seems to me that adding a salt, base or acid would be counterproductive. No?
