Ph of fe2o3
Webb30 juli 2024 · Fe reacts with oxygen to give Fe2O3. The balanced chemical equation for this reaction is 4 Fe + 3 O 2 --> 2 Fe2O3 Now from the balanced chemical equation we see There are 4 moles of Fe. We also see there are 2 moles of Fe2O3. So their ratio is Fe : Fe2O3 = 4 : 2. Simplifying by diving by 2, we get Fe : Fe2O3 = 2 : 1 Webb5 juni 2016 · The pH was measured using a pH meter (Thermo Orion 720A+) equipped with a Mettler Toledo Inlab 437 pH combination electrode.
