Is there such thing as.......

[mhhauser]

Can anyone tell if there is such thing as copper burn or maybe its call calcium burn I don't know if you guys know would you explain it for me or tell me a article that will

i don't recall from any of my chemistry text that any compounds including copper that will burn. but there is a compound called copper nitrate(CuNO3) that will leave a stain on your skin for quite a while and it's supposedly to be cancerous, but new born babies gets a drop of this stuff in their eyes to fight off infection.

as far as calcium...the only thing i can think of that would burn would be calcium hydroxide(Ca(OH)2). it is made through an endothermic process which means when we react(mix) it with water, we're breaking bonds and taking it from a higher state of energy to a lower one which would lead to an exothermic reaction(heat releasing) which will cause burns if handled unappropriately. hope that helps.

???Though it was silver nitrate, AgNO3???

I know calcium hydroxide or Kalkwasser is caustic, since the pH is so high. It is also carcinogenic.

correction, it is silvernitrate i was talking about. i was thinking about something else when i replied, my apologies.

i don't think calcium hydroxide is carcinogenic.

What about on the fish is there such thing for a copper burn or calcium burn on the fish.

You are right, I was thinking of diatomaceous earth.

it contains silica
