When \[{{H}_{2}}{{O}_{2}}\] is added to blood, rapid evolution of a gas occurs. Explain.

Answer:

                The enzyme present in the blood catalyses the oxidation of \[{{H}_{2}}{{O}_{2}}\] and hence rapid evolution of \[{{O}_{2}}\] takes place. \[2\,{{H}_{2}}{{O}_{2}}\xrightarrow[\text{in}\,\text{blood}]{\text{Enzyme}\,\,\text{present}}\,2\,{{H}_{2}}O+{{O}_{2}}\uparrow \]
