REFLECTION MAKING pH INDICATOR

From
this experiment, it is a very interesting experiment to be conducted in
practical class. By doing this experiment, I know the basicity or the acidity
of the household substances that we use every day. For example, I knew some of
the substances that I use every day is too acidic, or very alkali. So, in the
future, I will try to avoid the use of the substances, as, from my previous
knowledge, something that is very acidic or basic is not suitable to apply on
the skin. In addition, in our practical class, there are varieties of
substances that we tested. So, besides the things that my own group used, there
are another substances that our group do not covered but done by the other
groups. Lastly, I have a very wonderful teammates. They are easy to co-operate,
I am very happy to work with them. All in all, everything is fine.
Thank
you.

During this project, I am glad that our group was
still able to keep up with the schedules given and complete the task in
appropriate time. Cooperation is
important in every group works and I believed that all members of my group have
shown their most cooperation. We divided our workloads by bringing different
type of household products that will be used in this experiment such as
shampoo, cleanser, hair conditioner and so on.
Good interpersonal relationship between the group
members enables us to communicate effectively and hence working efficiently
within the group. On top of that, working in a team would also need qualities
such as responsibilities, disciplines, empathy and corporations. And I can
assure that all my teammate have shown such qualities throughout the project.
In order to produce a proper laboratory report, we divided our work loads into
parts such as introduction, results, discussion, conclusion and so on. Hence,
it is easier for us to compile it together later. Our group was able to work closely
and had constant communications on online WhatsApp after class in order to
finish our task.

Assalamualaikum and hello everyone, for this week we
are doing the lab project for Application: Making pH indicator. In this lab we
are gone make our own pH indicator to test the pH range of the indicator and
also to test the household chemical. For this experiment all of group need to
bring flower and 5 type of household. First is we need to extracting the indicator,
we use two different indicator which is purple cabbage and purple flower. After
that the extracts from the two indicator have been used to test the pH range
for each indicator. Last but not least, we use the indicator to test the pH of
household chemical. The household that we bring is toothpaste (Colgate),
detergents (Attack Perfume), soap (Mareah), conditioner (Sunsilk) and soap
(Shurah). This experiment help us to know the pH of each product that we use.
For the example is the conditioner that I use, the pH is 3 (purple cabbage) and
4 (purple flower). This show that the product is really acidic and I did not
know before this which is really dangerous for my hair. This experiment really
help me to know which product is suitable to be use and which one are not
suitable to been used for ours daily day.
Thank you.
