b) Given the following reactions draw a p-pH diagram for aluminium. Assume a concentration of 10-6 M for Alt. For purposes of drawing the water oxidation and reduction lines, assume H2 and O2 each are present at 1 atm. Your plot should extend from pH 0 to 14 and p from -45 to +18. Al3++3eAl(s) = Al2O3(s)+6H6e2Al(s) + 3H2O = AlO2+4H+3e Al(s) + 2H2O = 2A13+ 3H2O Al2O3(s) + 6H+ Al2O3(s) + H2O=2A102 + 2H+ E = -1.66 V E -1.55 V E = -1.26 V K-10-11.4 K-10-29.2
