Discussion on Oxidation-Reduction Reaction

The transfer of one or more electrons involves in the oxidation-reduction reaction also known as redox reaction. For energy production photosynthesis as well as most reaction is used in redox reactions. For the calculation of redox reaction, for the indication of charge of an element oxidation states are used. By assigning electrons it is done for general atoms as well as in the reaction it is also used to keep in tracks the electrons. To assign oxidation a series of rules is used usually H has a positive charge and oxygen has -2 charges. It is said to be reduced when the charge on an element is decreased as well as the element which receive the element are known as oxidizing agent.

If the charge increase on an element that’s called as oxidizes as well as the compound it is the part and it is said to be the reducing agent as it gives off the electrons. By using the half-reaction method in a redox reaction the balance of an equation is calculated. Into two half reactions the reaction is separated; one is reduction and other is oxidation. Heat is produced in redox reaction as well as if the reactants are separated current could be created from the reducing agent the oxidizing agent that require the transfers of electron to occur via wire. After that the current go through the device also create the electricity. At zero to keep the net charge solution ought to be connected to permit electrons to flow and buildup prevent.

The observation we made in the lab experiment we divide the lab into following step. In every oxidizing reducing agent experiments first of all we balance the chemical equation after that we find the concentration of unknown solution like Fecl2, in this experiment. Fecl2 10 ml solution is obtained from the unknown solution. 10 ml h3po4 also added to the same beaker that is used in part 1 and set this beaker aside. Then for the titration here we have three unknown solution and five different groups. When we start the experiment prepare the buret for use, rinse it with distilled water also with the solution of KMnO4. After that allow the solution to run out from the buret tip; after that rotate the buret white tipping horizontally and wash the walls of the buret.

Repeat this with the solution of KMnO4. While pouring this solution wear the gloves as it is corrosive.  We get 25ml of the solution of KMnO4 also add to the buret. After that measured the initial volume of KMnO4 with the help of piece of paper. After some time you observe that the color is change. Then it takes time to fade, also add the smaller volume of solution KMnO4. From yellow to pink and then pink to persists the color is changed its mean you have reached the equivalent point. This is only happen the amount of acid and base is equal. Record the value that you get during the experiment. For the test titration add extra drop of the KMnO4 then the second color is become purple its means that we titrated this solution many time we don’t want this solution. And for the next titration waste off the solution that present in the buret. After the experiment record all the data.

In the air, oxygen become the source of error could have contributed within the reaction as the oxygen have the higher morality that helps in contribution and tells that weather the compound is reduced or oxidized. Inaccuracy of the scale also the source of error, a different result is found when measured it always and also change the molarity of the solution.  

Conclusion on Oxidation-Reduction Reaction

Objectives of the experiment were to see that how redox reaction works and how it plays a part in our daily lives, how we obtain energy through redox reactions. Another objective was the learning technique of titration method that how this process works and how one can know the concentration of an unknown solution through this technique. Last objective was to know about the errors that can take place and due to which results can get damaged. Results of the experiment were to know about the concentration of FeCL2 solution by the use of titration method which was being started from taking a small concentration and ended up with a complete given solution.

The interpretation of this experiment was that how the concentration of the unknown solution can be determined by the use of a technique known as Titration method and what things should be taken care of while performing it. Another interpretation was to know about the redox reaction which is taking everywhere around us. This experiment was very interesting and it helped me learn a lot about the techniques which I was not aware of. I came to know about the different equipment and how to use them in the performance of any experiment. How one should be careful and what kind of errors can take place and how these small errors can affect the results within a seconds. One should be patient and careful enough while doing any experiment in the lab. Make sure not to perform any experiment in a hurry. I came to know that how concentration of different unknown solutions can be determined and what basically is an oxidation-reduction reaction.
