Question

Hydrolysis of aluminium and bimuth in nacl solution

Answer 1

Aluminum has a low nuclear weight  

3 valence electrons,  

what's more, high movement. It is likewise cheap . The response of 1 mol of aluminum with water can create 1.5 mol of hydrogen.However, the hydrolysis of the ball-processed Al−Bi compounds in methanol and ethanol compares to just a little or even no hydrogen generation. The hydrolysis instrument of the Al−Bi amalgams depends on the microgalvanic cell between the anode (Al) and cathode (Bi), so the high ionic conduction of the media assumes an essential job in enhancing the Al reactivity. Bi can actuate Al, and a higher substance of Bi metal can quicken the hydrolysis rate of Al.
