Suppose that a 2.0 cm2 sample of iron is immersed in 500 ml of acid solution and the corrosion rate is determined by Tafel extrapolation to be 10.0 mA/cm2 . Assume that the iron corrodes to form Fe2 ions with the evolution of hydrogen. After a 10 h immersion period:
(a) What is the total concentration of dissolved Fe2+ in solution?
(b) What is the weight loss of the iron specimen per unit area of sample?
(c) What volume of hydrogen gas in ml (STP) has been evolved per unit area of sample?
