Oxalic Acid Lab Report

Procedure: To begin this experiment all of the equipment was collected. The materials used in this experiment were a small plastic weighing dish, oxalic acid, a 250 mL Erlenmeyer flask, distilled water, a buret, NaOH solution, a 150 mL beaker, funnel, and phenolphthalein indicator. Before the experiment began the buret was cleaned with distilled water, a buret brush, and dish soap. The buret was completely washed out in order to not cause any faults in the results of the experiment. Once the buret was cleaned 10 mL of NaOH solution was drained through the buret and stopcock to make sure it is completely cleaned. Then more NaOH solution was obtained in the 150 mL beaker. The NaOH solution was then poured into the buret using a funnel until the amount of NaOH solution was …show more content…
The initial volume of NaOH in the buret was collected. Next, the oxalic acid solution was created. An analytical balance is used to measure the amount of oxalic acid. The small plastic weigh dish was placed on the balance and the tare button was pushed in order to reset the balance to 0.0000g. By doing this the mass in grams of oxalic acid was shown individually. Oxalic acid was poured carefully on the balance, between 0.4000- 0.5000 g. The amount of oxalic acid poured was recorded, and then transferred into the 250 mL Erlenmeyer flask. Crystals of oxalic acid still on the small plastic weighing dish were removed using distilled water to rinse them into the flask. Next, 50 mL of distilled water were placed into the flask. The solution was stirred until all of the oxalic acid crystals were dissolved. One drop of phenolphthalein indicator was then added to the 250 mL Erlenmeyer flask. The flask was placed under the buret and the titration began. Turning the stopcock drops of the NaOH solution began to drop into the oxalic acid and phenolphthalein indicator solution. Once neutralization was reached the oxalic acid and phenolphthalein indicator solution turned pink and the
