A piece of aluminium plate is submerged in a 1 M hydrochloric
acid solution. It was
observed that the metal piece slowly disappears and hydrogen gas
bubbles on its surface.
Assume the atomic mass of aluminium is 27 g/mole, Avogadro’s number
is 6.023 x 1023
/mole , and charge of an electron is 1.6 x 10-19 C. Calculate how
much aluminium is
dissolved in 3 hours when the corrosion current is 5 mA.
