screwed my chem practical today !
cause i was shaking like a leaf. ( exaggerating. )
i was realy nervous.

here goes--

1. i held 6test tubes to put into the test tube rack.
when i was ab to put 1test tube inside, it broke. =x
so i stared at the test tube & it stared at me.
we were grinning at each other. B)

kidding. i was shocked & was i was wondering if i should tell the teacher.
i told her after 10mins?

yup, so i broke a test tube when the exam started in less than 5mins.

2. after warming the first test tube with the thingy in it, i used a litmus paper to check for any gas. i put in the litmus ( w/o touching the sides of the test tube ) & tada ! the litmus dropped into the test tube.
so it turned to red completely.

well done charis. =x

QA went smoothly after that.

*proceeds to VA*

3. titration was badly done.
first try- was ok.
second try- solution Q only turned colourless when solution P was below the readings of the burette.
no number on the burette = redo.

a. didnt know why Q had so many bubbles when i pipetted Q up. so i kept trying.
b. didnt know what i did to the red thingy & some green ppt came out of it.
-.-
& my solution Q became yellow.
so i had to call for the teacher & changed my solution.

after trying for 10000 times, i finally completed my 2tries
& i got P's reading - 25.5 cm3 .
