This study involves the use of redox titration to determine the amount of oxalic acid in the sample solution. The analyte solution containing oxalic acid was added with sulfuric acid and heated prior to the titration with permanganate. The persistent pink color signaled the end of the titration. The amount of the oxalic acid in the solution was found to be 8.941%. The redox titration was precise in the quantification of oxalic acid with a standard deviation of 1.327%.
Introduction
One of the natural organic compounds found in plants is the oxalic acid. It is commonly found in leafy greens, and nuts, as well as in some fruits. Spinach is known to have the highest amount of oxalic acid in vegetables of about 750 mg for every 100 gram serving (Oxalates In Spinach – Is Oxalic Acid A Green Smoothie Health Concern?, 2015). The usual amount of oxalic acid that people usually take in is not toxic and harmful. The danger, however, is when oxalic acid exceeded the maximum allowable limit of the human body. Oxalic acid can produce kidney stones by reacting with the calcium in the body. This does not only results to kidney failure but also reduces the amount of calcium that must be absorbed by the body. …show more content…
The titration process is under the quantitative branch of chemistry, called analytical chemistry, which aims not just to determine the component but also to quantify the amount of the component in the sample. Redox titration is an analytical method which is based on a chemical reaction between an oxidizing agent and a reducing agent. Permanganimery is a common redox titration component because of its high standard reduction potential, making it a good oxidizing agent. Permanganate reacts with oxalic acid according to Equation
