On the reaction of hydrogen peroxide mixed with hydrochloric acid
The change in the mixing of hydrogen peroxide and hydrochloric acid must be investigated in detail. Hydrogen peroxide, whose formula is $H_2O_2 $, is oxidizing and can also be used as a reducing agent, because its valence state of oxygen is in the middle. Hydrochloric acid, $HCl $is also, in common cases, a strong acid, which can dissociate hydrogen ions and chloride ions.
When the two are mixed, there may be a slight heat at first. Hydrogen peroxide encounters acid, and its molecular structure changes slightly. The hydrogen ion supplied by hydrochloric acid can affect the ionization equilibrium of hydrogen peroxide.
From the perspective of redox, the valence state of oxygen in hydrogen peroxide is -1, which can rise or fall. Chlorine in hydrochloric acid is usually - 1 valence, which is its lowest price state and has a certain degree of reduction, but it is relatively weak. In the mixed system of the two, hydrogen peroxide may oxidize chloride ions. The reaction may be as follows: $H_2O_2 + 2HCl\ rightarrow Cl_2 ↑ + 2H_2O $.
In this reaction, hydrogen peroxide acts as an oxidizing agent, and the valence state of oxygen decreases from -1 to -2, while chlorine in hydrochloric acid is oxidized, and the valence state rises from -1 to 0 to generate chlorine gas. Chlorine gas, a yellow-green gas, has a pungent smell and is toxic. Therefore, when the two are mixed, if this reaction occurs, it can be seen that the yellow-green gas escapes.
However, the occurrence of this reaction is also controlled by many factors. For example, the concentration of the solution, if the concentration of hydrogen peroxide and hydrochloric acid is low, the reaction rate is slow or barely observable. Temperature also has an effect, and increasing the temperature may promote the progress of the reaction. And if there are impurities in the system, it can be used as a catalyst to change the route and rate of the reaction.
In general, hydrogen peroxide is mixed with hydrochloric acid, depending on the conditions, or a redox reaction occurs to form chlorine and other products. To observe the change, it is necessary to study all ends carefully to understand the chemical principle.
