Is always the negative electrode of the system (true or false)
Always has a negative potential vs SHE (true or false)
Is always a reduction site (true or false)
An electrolysis process is carried out between an electrode with a surface of 1 m2 where the current density is equal to 1 mA/cm2 and an electrode whose active surface is a 10 cm x 10 cm square. What is the absolute value of the current density at this second electrode?
