Question 1 - how severe is this reaction? Why does it happen? can
someone please give me an explanation, kind of an idiots guide
Question 2. If copper and silver (or any other metal) react so
badly together - what happens to the copper content in sterling
silver? or is this somthing to do with the alloy created?
Answer to question 1 should take care of question 2.
In order to answer question plainly, I am going to have to dispense
with some formalities. Please bear it in mind when making
Put together metal and liquid and liquid would contain 2 types ions -
positive and negative. (An ion is an atom where balance between
electrons and protons has been shifted, creating electrically charged
When 2 metal are present, ions of one would have different
electrical potential than the other. When potential is present, ions
will flow to equalize the difference. Since metal would supply ions
into solution constantly, equalization is not possible until metals
are present, so one metal corrodes the other.
Sterling silver can be looked at as silver corroded with copper. If
we let the above described reaction to continue for very long time,
the result will be somewhat similar to an alloy. ( I am using term
alloy very liberally ).
