REFLECTION ACID BASE TITRATION

REFLECTION ACID BASE TITRATION

First and all, when we were doing this experiment, I got to know the apparatus that I used during conducting the experiment, for example, burette and pipette. During conducting the experiment, we did use both of the apparatus, before this, I always get mistaken between those two, but after the experiment has conducted, I recognized that both of the pipette and burette and have distinct differences. During the experiment, our patience and determined were also tested. This is because, when we conduct the titration of phosphoric acid with NaOH, it took a lot of time and very small changes were recorded. That cause all of us to repeat the same processes over and over again to obtain the desired result. During conducting the experiment, we ought to be very precaucious about the apparatus we are going to use. When we were going to use, for example, the pipette for measuring the liquid chemical, we were asked to wash the apparatus with the solution itself to avoid contamination and so as to obtain the most accurate result and to minimize the error because we need to draw a graph for the result.

Good day everyone, after we have finished our experiment we were assigned to write on reflection about what we have done, what process that we have go through and few more aspects.
Since this is the first experiment for this semester, we were thrilled to work as a group after haven’t meet each other during the semester break. I felt that our group did a wonderful job and we distributed the workloads fairly. We were able to keep an eye on our experiment closely and make sure they were right on track.
Furthermore, I’m glad that our instructor being so helpful and this make our experiment run smoothly. The major benefit of working in a team for me was that it facilitated learning and enhanced my understanding of the topic. I have definitely gained more understanding about the topic from my teammate compared to what I have learnt in class. We discussed about the problems and each of us contributes ideas on how to solve them.
Last but not least, our experiment went well. My team members and I felt free to share our ideas and knowledge with each other, and that definitely made my learning process more interactive, interesting and enjoyable.
Thank you.

            Assalamualaikum and hello everyone, this week we conduct the acid base titration laboratory. Where we need to record the data about how much NaOH that be use to get the pKa value for acetic acid and phosphoric acid. I need to make a reflection about the experiment that have been conducted. Thanks to the instructor that help me and give a good explanation about how to conduct the experiment. We did not have any problem during conducting the experiment. Besides, I will also like to thank my group member because give the good teamwork during conducting the experiment. What I learn from the experiment is that how to use the pH meter in the correct way. I also know how to doing the titration in the right way. There are many precaution step that need be taken during conducting this experiment. Before we use the pH meter to take the pH value of the solution the tip of the pH meter need to be rinse with distilled water because it really sensitive to the pH . The pH value that our group get is not same as the theoretical value that state for both acid, that show that are some error during conducting experiment.

Thank you.
