Al(OH)3 + H+ = Al3+ + H2O. MnO2 + H+ = Mn2+ + H2O. FeOOH + H+ = Fe3+ or 2+ + H2O reduction rxns. Acid soils are more sensitive to strong acids since the ... The turn-on fluorescent sensing Al3+ based on PET and ESIPT was studied. Abstract. A diarylethene derivative has been synthesized by attaching a ... Since it is easier to reduce H2O than Al3+ the water reaction will occur at the cathode. Anode reaction. 2F- → F2 + 2e-. E°= -2.87 V. H2O → O2 + 4H+ + 4e-.
