is the process of reacting acid and metals together in order to have the release of the ions of the metals into the acid either for the purpose creating a small voltage that can be detected by galvanometers or for the purpose of a particular metal.
that is meant to produce voltage will usually comprise of two different metals with the one serving as the not reactive to the ions of the , an example of such is when (from normal radio battery) acting as the is inserted into a bow containing tetra-oxo-sulphate(iv)acid and zinc plates folded together acting as the is also inserted in the same bowl at the opposite direction while the end of the of these two terminals are fixed to a galvanometer, the result will be a release of followed by the release of zinc ions into the bow solution while the galvanometer will be indicating the small voltage in the setup, which is usually from 0.1volts to 0.5 volts.
While the that is meant for would consist of two metals of different reactive strengths, a solution of one of the metal to be used in the of the other, they will be setup in the same way the above for voltage is set up, by having the bow filled with the solution of metal that would be other metals, example chromium is one of the metals normally used for , to electroplate an iron spoon with chromium, put chromium solution in a bow and insert a chromium rod into it as a , and put the iron spoon into the solution at the opposite side as the , then connect the terminals to a primary cell. The result will be a rapid release of chromium ions into the chromium solution by the chromium rod while the iron spoon acting as the will receive the ions and have its body covered by the ions. The longer it stays the thicker the coating of chromium on it.
In the course of performing these experiments, there are safety precautions one must put into consideration, and failure to observe them can cause the following;
I conducted an in a and after the , the list effects were what am going to discuss. A cough that seemed as though something entered in the walls of my throat with the little feeling of dryness in the throat, the situation lasted for about 20 minutes after the . Though I cannot categorically point the cause of such reaction but I do suspect that I might have inhaled vaporized coming out from the beaker I was using during the .
I observed that the following day I started , the lasted for a whole day, that was when I decided to trace why such could lead to my but I could not exactly figure out why it happened, the only thing that does come to my mind was that the is very small with only one small window and the only door it has was closed during the in order to avoid distractions, may be the vaporized might have filled the atmosphere in the such that I was inhaling it without knowing.
Irritation in the eyes
Another body reaction I observed was eyes irritation just immediately I finished the but the reaction stopped later after I washed my face with water. Though its duration was very short I concluded that I did not conduct the properly, maybe I should have created a means for the gasses to escape easily out of the .
I noticed itching on my skin though not a serious type put it lasted for some time even after washing my hands with .
With all these experiences and encounters I would recommend putting the following into consideration before conducting the experiments;
Use rubber hand gloves
Wearing hand gloves will ensure that direct contact with the acids is completely avoided, which could help in eliminating .
Cover the nose
Wearing nose is another way of preventing the vaporized from entering your nose if such device is not available tying the nose with a neat cloth can perform the same function.
Wearing of any kind will help to reduce the entrance of gasses into the eyes.
Keep distance from the bow
Keeping a good distance from the area while observing the reactions and results is a better way of reducing any harmful effects the would cause to you.
With all these, you may not have any problem each time the is carried out irrespective of the duration of the .
