What do you suppose forms on nichrome wire upon exposure to air and high temperature?

Are those compounds soluble in water?

Will they react with HCl to form soluble salts?

Metals like nickel, chromium, aluminium form a protective oxide coating on its surface which prevent further corrosion. These oxides can be removed by dipping in HCl which will form water soluble salts after reacting with the metal oxides

hmm nichrome wire in air makes an oxide then it doesn't work too well. if i add acid i could clean that junk off.
