Hemoglobin (abbreviated Hb) is a protein that is responsible for the transport of oxygen in the blood of mammals. Each hemoglobin molecule contains four iron atoms that are the binding sites for $\mathrm { O } _ { 2 }$ molecules. The oxygen binding is pH-dependent. The relevant equilibrium reaction is

$$\mathrm { HbH } _ { 4 } ^ { 4 + } ( a q ) + 4 \mathrm { O } _ { 2 } ( g ) \rightleftharpoons \mathrm { Hb } \left( \mathrm { O } _ { 2 } \right) _ { 4 } ( a q ) + 4 \mathrm { H } ^ { + } ( a q )$$
