Introduction:
The following experiment explores LeChatelier’s principles. By changing factors of the principle such as temperature or the concentration of the reactant, we investigate whether equilibrium is achieved through the visible changes that can be observed and measured. Such measurements involve the change in color or the change in pH value of the solution. Hence, in order to understand the following experiment, it is necessary to fully understand the concept of chemical equilibrium and LeChatelier’s principles.
The establishment of chemical equilibrium requires fulfillment of certain conditions. Macroscopically, it seems that the reaction is static. However, when the reaction is observed microscopically, it is actually dynamic. Hence, chemical equilibrium is also known as dynamic equilibrium, where the rate of forward reaction equals to the rate of backward reaction. LeChatelier’s principles explains how chemical equilibrium is established in the presence of external stress.
