Qualitative Analysis Test

8 days to go.
examination.

Today is our first qualitative analysis test.
Quite excited about it. haha.
But, a stupid things happen.
here the story.
We must bring our lab coat when we had this test.
Last night i remember it(lab coat) need to bring.
When morning, I put it beside my bag. I remember it.
But don't know why i forget to bring it to school.
And i can't remember i forget to bring the labcoat.
When we want to go chemistry lab,
i discover i didn't bring it, I'm so nervous,
I called Gloria to accompany me to call my mum to help me bring it to school.
Luckily my house beside the school, very near. ^^
My mum throw the lab coat over the "great wall" between my school and my house.
Gloria keep laugh, laugh and laugh. hahaha =D
Hoo, so lucky.


the "great wall" between my school and my house. 

Then, when qualitative test,
My first medicine (chemical) is white powder and insoluble in water.
I added nitric acid to dissolve it, but it can't dissolve.
I almost used 20 minutes to dissolve the chemical but i can't.
So i just use the undissolve chemical. *stupid!*
I really want crazy when dissolve the chemical, really.

My 2nd chemical, Blue salt and soluble in water.
Yeah. =D
but don't know why i test the cation,
2 answer appear. Nitrate or Sulphate.
So i test nitrate again and shows that the chemical in nitrate.
But, francis say is sulphate. Oh no. =(

Ok, other topics.

Bingo! A cat.








Ok, ends here.
