3 cheers for Mr Ho! YAY~ :D

-DPCS Year 2s

Hello! We're back again!:D
For this week, we carried out an experiment for Colloid Chem which is to test the stability of 2 types of colloids, that is the Gelatin colloid and Hydrated Iron(III) oxide colloid~
Here's a picture of the gelatin colloid which hasn't been destabilised yet. Looks clear right?:)

Now, here's how a destabilised gelatin colloid looks like. It's looks turbid just by the addition of approximately 1mL of ethanol;)
Next, here's how hydrated iron(III) oxide colloid looks like when it hasn't been destabilised yet:)

Hello! We're back again!
So for this week, the year 1s got a chance to carry out standardisation of  HCl against Sodium Carbonate which is a primary standard!
Here's the picture of HCl which was contained inside the volumetric flask~
We carried out titration against the sodium carbonate primary standard in order to find out the exact concentration of the HCl.

We added in 2 drops of methyl orange indicator to the primary standard before we begin titrating. So this was how it looks like before the start of titration~
During, the titration process, we titrated the solution of sodium carbonate in yellow with the HCl from the burette.

At the end point, a nice orange solution was observed!
We also had to be extra careful not to over-titrate the solution!:)
Aside from the lab sessions, the year 1s are also busy gearing up for the upcoming MSTs:)

Till we meet again next week!

 She likes to have her picture taken. *face palm*


 Anybody got the free cone from burger king too?

 star anise!

Flavor & fragrance chemistry. Fun fun fun! This week we focused on the spicy essential oils. :D
MST is getting nearer & nearer. EVERYBODY LETS WORK HARD TOGETHER! :)

Hellooo! We're back again!
So, basically for this week, it's 02's turn to make their own cold cream!~ Weeeeeeeee~
It was so much fun! And guess what? Some of us came out with REALLY NICE pastel colours like Pink and Yellow (It looks like yoghurt and ice cream too:D) NICE, isn't it? ;)

Cold cream aside, most of the year 1s this week are busy editing and making their final touch-ups to their skincare report before submission. Not to forget, we're busy preparing for our upcoming tests and MSTs too~

Looks like we're going to have a busy week ahead!

Till we meet again next week!

HELLO EVERYONE!
One week passed in the blink of an eye & its time to update the blog again! :)
Missed us? Hope you did! ;)
Here are some photos (sorry for the poor ipod touch quality photos by the way) taken at school!
This is how perms actually work. COOL ISN'T IT?! 


Don't be fooled by the photos above. Studying is not the only thing we do. We all have fun too!

Our fellow classmate. Such a pretty photo, isn't it?
No she isn't pulling her hair due to stress. (I think XD )

Not forgetting our usual smelling exercise! :) Flavor and fragrance chemistry has got to be one of the coolest modules we study here in DPCS! Please ignore that pack of hello panda on my classmate's table! >.>
Please look forward to our post next week as we'll be having some cool practicals! :D
Take care!
