In a solution of FeSO4, solution of .02 KMnO4 was added until the combination of the solution turned pink. The change of the color pink indicates that the reaction is complete. The process that was undergone with FeSO4 and KMnO4 is called titration. In chemistry, titration is a procedure used to determine the molarity of two or more solutions. Molarity is the number of moles in a compound in a solution over the number of liter in the solution. In titration, solution of known quantity and concentration is enumerated to another solution of also known quantity and concentrations until an end point of combined solutions are reached. The end point is nothing really that fancy but rather an indicator of color change, which represents that the reaction is over. In the titration, the two substances exchange electrons, which can be called redox reaction. In redox reaction, one element or compound is reduced and gains electrons, while on the other hand, the other element or compound is oxidized and loses electrons. For this lab, through the given oxidation and reduction numbers from balancing the equation and the electrons, it was shown that Manganese was reduced while Iron was oxidized. Also from the equation, the movement of electrons can be noticed, as it was added or subtracted from the substances. In order to balance an equation, there must be same number of elements on both sides, with the exception of hydrogen and oxygen. From there, in order to balance oxygen, water molecules are enumerated to the opposite of the equation/reaction. Then from there, the Hydrogen ions need to be balanced, so the same numbers of Hydrogen ions are added to the opposite of the equation. Then it comes to the electrons, the same number of electrons added to a substance in the reduction half of reaction is taken away from the substance in the oxidation of half reaction. The last step is to add them together, whatever is on one side stay together and whatever is on the other side also stay...
