How am I doing?
During the experiments, I learned a variety of skills that will serve me well in university and in the future.
These abilities will be useful to me in university, where I hope to study forensic science and later work on a
criminal investigation team. This subject interests me because I have learned that if I apply these skills,
particularly chromatography skills, to my future cases, I will improve my practical skills in criminal
investigations.
These abilities will provide me with more guidance and experience in the future. I performed titration,
calorimetry, colorimetry, and chromatography while theorizing and studying the techniques of these
experiments' practical procedures. However, in order to carry out these experiments, I had to draw on my
previous experience and knowledge. For example, consider the hazards and risks that may affect me and
my peers, as well as the experiment. But I needed to brush up on my prior knowledge. Looking back, I can
see how sharing my previous and new knowledge with my peers helped me expand my skills and advance
my teamwork abilities. As a result, I must put these abilities to use in order to assist my peers.
I’ve learned many skills in this unit. Because I lacked prior knowledge and technique for dealing with the
equipment as well as the risks and hazards, this has been proven to be extremely critical and important as
a whole unit. on how to apply these new skills while conducting the experiments. These skills will then be
transferred and applied to future skills and modules that I’ll learn and apply. For example, how to use
individual equipment, health and safety, risks and hazards, following procedures, collecting data, analyzing
data, calculating results, and comparing results will be used in future laboratory experiments and
coursework.
Overall The Main Skills I Have Developed In Unit 2 Are :-
- One skill I have developed is leadership - guiding my group in every experiment . During titration my
peers were confused on how to set up the burette and how to handle the pipette . So , I guided my
peers step - by - step through the entire unit . This means I can use this new developed skill in the
future and improve it further onwards .
- Another skill I've honed is analysing and comparing my results to those of other groups. It aided me
in researching and analysing the risks, health and safety benefits of each experiment. As a result, it
can provide me with guidance on what precautions to take and assist me in the future when
conducting research on criminal investigations and analysing evidence.
- One other skill I have developed is communication . Communicating with others helped me clear my
doubts about this unit and get feedback on my coursework .
- Another skill I have developed is presenting data . Collecting and presenting every piece of data in
one document ; and laying out every information in a neat structure .
- Another skill I have developed is observation , I have observed my teacher demonstrating every
experiment . Having a clear understanding on what to do .
Key Skills I’ve Gained and What Skills Did I Apply: Titration :-
This experiment has taught me the importance of calibrating equipment. We practiced calibrating the
weighing scale, pH meter, and pipette. Because calibrating the device can assist us in determining whether
our equipment has been tampered with or damaged, this can have an effect on our measurements in the
experiments, resulting in erroneous data. Measuring a quantitative mass aided in the calibration of all the
equipment and the preparation for investigations.
Another important skill I've acquired is how to use the burette. When we had to close the tap during the
experiment, we had to do it quickly; otherwise, an excess amount of hydrochloric acid (HCl) or sodium
hydroxide (NaOH) would have been introduced. So we made practice runs for experiments to improve our
handling skills and to close the burette on time when the timer reached 60 seconds. I used my previous
1
, understanding of conducting titration experiments for the acid and alkalis topic throughout the titration
experiment. This was quite beneficial to me because I already had some basic understanding of risk and
hazards in the workplace.
Calculating the concentration of each solution used in each experiment is another important skill I've
learned during this titration experiment. Finding the concentration, for example, equals moles divided by
volume. These calculations assist me in determining the ultimate outcomes of each experiment. I used my
prior calculating techniques to get the % yield or mean titre, and then I compared all of my results to other
groups' or public data to see if there were any differences or parallels in our findings and processes.
because we may have used alternative measures or prolonged the time to close the burette tap on time.
Another important skill I've learned from this investigation is detecting potential dangers and threats to our
health throughout the titration, chromatography, calorimetry, and colorimetry experiments. I had to analyze
the dangers of each chemical, make a risk assessment, and determine what precautions should be
implemented. A major ability I've used is my past knowledge and research on how to layout coursework in
a Word document. For my GCSEs, I studied BTEC Business. It was quite useful in producing a risk
assessment, assessing the danger level of each chemical and piece of equipment, and learning how to
handle the substances and equipment cautiously. In the past, I completed a lot of coursework and studied
for most of my business lectures.
What I've Learned and What Skills Have I Used: Colorimetry :-
I learned how to utilize the colorimetry machine during this colorimetry project. During an observation, my
teacher explained how to use the colorimeter, how to insert my solution in a cuvette, how to change the
wavelength to a specified level, and how to read the absorbance level of copper sulfate. My ability to
observe is one capability I've used. This aided me in having a clear comprehension and writing certain
critical notes to have a comprehensive grasp of my colorimeter machine handling approach. This implies
that I may use the colorimeter machine in the future. This talent also greatly aided me in broadening my
knowledge and developing it into a practical skill.
Another skill I've learned from this exercise is calculating the beer-lambert law. Because it provides the
ultimate absorption value of copper sulfate. This new expertise will aid me in future experiments and in
writing up proposals for new units. My arithmetic abilities assisted me in determining my final colorimetric
result and discussing how high the concentration of copper sulfate (CuSO4) is. This means that estimating
the concentration of copper sulfate (CuSO4) will help you determine the concentration whether the solution
is diluted or a pure chemical property.
Key Skills I’ve Gained and What Skills Did I Apply: Calorimetry :-
During this experiment, I learned how to utilize the heat bath. We had to melt paraffin wax and stearic acid
during the calorimetry experiment since it's difficult to monitor the temperature while it's solid. I looked into
ways to regulate the temperature of the heat bath. One talent I utilized to acquire this new skill is my
observation skill, which allows me to correctly comprehend how to manage the equipment in experiments.
Because they are vulnerable depending on how we handle our method.
Drawing graphs of my data is another ability I've acquired as a result of this endeavor. Because it is simpler
to read the findings. This also helped me compute the tangents in all of my graphs. We have to make a
graph since it is easier to visualize all of our data as one smooth curve. One ability I used in this experiment
was my prior understanding of how to draw a graph and my math skills, since I had to calculate the
tangents of the graphs and plot my results on the graph as well as draw a straight line. This enabled me to
quickly determine the maximum and lowest melting and boiling points, which will aid us in determining the
physical condition of stearic acid.
One other skill I've gained in this experiment is using two thermometers simultaneously. During the
calorimetry experiment, we had to calibrate the thermometers to check if they were working in perfect
