Talk:Nickel(II) oxide

Untitled
I am trying to figure out the intent of this statement or considering ways to make the statement clearer: "Conditions/substances to avoid are: fluorine, hydrogen peroxide, hydrogen sulfide, iodine, barium oxide + air, calcium oxide + air, aluminum, aluminum chloride, ethylene, p-dioxan, hydrogen, methanol, non-metals, oxidants, sulfur compounds, dilute hydrochloric acid, dilute sulfuric acid and nitric acid" Who is supposed to be doing the avoiding and why? Is this information relevant to NiO, otherwise kind of innocuous stuff. I guess the goal is to explain what NiO reacts with? --Smokefoot 00:09, 2 June 2006 (UTC)

Looks of Nickel oxide on a polished surface
Many brass and woodwind instruments (like saxophones) are plated with nickel, it would be interesting to know if nickel oxide appears on polished surfaces, and if it can be avoided by eg cleaning?

also if it would appear more quickly on surfaces that are in touch with the skin (acidic sweat or skin oils) or not.
