Yes it is corrosive to skin. The Safety Data Sheet identifies it as Category 1A for skin corrosion, which means: A substance that, according to animal data acquired from a scientifically validated method, produces irreversible damage to the skin after an exposure of three minutes or less, and within one hour of observation, in at least one of three animals....

Approximately 0.01 hour of searching, including the time taken to type in the search words, reveals this on Wikipedia: In hot concentrated hydrochloric acid, aluminium reacts with water with evolution of hydrogen, and in aqueous sodium hydroxide or potassium hydroxide at room temperature to form aluminates—protective passivation under these conditions is ...

The answer is yes, you will get a potential difference of 0.2-(-2.37) = 2.57 V, if Mg and carbon filament are used as the electrode materials and connected into one circuit. The third digit after the decimal is removed, because different resources give slightly different values. From our own experiments using glassy carbon, its open circuit potential is -0....

Yes, I agree some electrochemical corrosion occurring. Per the picture, there is especially evidence of corrosion in particular spots, for example, at the end. My guess is that one of the contributing factors is your touching the ball resulting in the deposit of NaCl. With a change in temperature and humidity, you likely fostered the creation of an ...
