HI GUYYYS~
Hi so today i'll update you on what my class has done this week ~
Due to the HBL week most of the lab sessions for my class had been delayed for 2 weeks !
): boohooo!
So After 3 weeks, we finally did our skin care and analytical chemistry lab session yay ~
heheh let me update you with what we have done this week ^^
Some photos of what we were doing for analytical chemistry lab ~
heheh look! have u seen such a pretty toothpaste ~ ;p
Can you guess what are we going to do ?:)
so all this are the solution prepared ! Naoh and HCl ~
so 10ml of HCL was pipetted in to this conical flask and toothpaste was mixed into the conical flask too ~
so we are going to heat the solution now yay ~
When bubbles are produced we have to remove it from the hot plate and let it cool to room temperature ~
So 2 drops of methyl orange are added
TADAHHH! It turns into pretty pink bandung colour hehe
now to the titration part ~ The indicator will reached an end point which is ....
ORANGE COLOURRR ~~~☺
so if u over titrate it will become like this orangey yellow colour ):
AND YOU WILL have to redo the experiment again like me ):
