一、海水电池例1 1991年,我国以铝-空气-海水为能源的新型海水标志灯已研制成功,这种灯以海水为电解质溶液,以铝合金为负极,金属(Pt/Fe)网为正板,靠海水中的溶解氧使铝不断氧化而源源不断地产生电流,只要把灯放入海水中数分钟,就会发出耀眼地闪光,其能量比干电池高20～50倍,其总反应式为:4Al+3O2+6H2O=4Al(OH)3,试写出电极反应式.
First, the seawater battery example 1 In 1991, China’s aluminum - air - seawater as the energy of the new seawater marker lamp has been successfully developed, this type of lamp seawater electrolyte solution, aluminum alloy anode, metal (Pt/Fe) net The positive plate, relying on the dissolved oxygen in the seawater to continuously oxidize the aluminum and continuously generate electricity, as long as the lamp is placed in sea water for a few minutes, it will flash dazzling flash, its energy is 20 to 50 times higher than the dry battery, the total response The formula is: 4Al+3O2+6H2O=4Al(OH)3. Write out the electrode reaction equation.
