Hahaha... Ok, running out of stuffs to type. So, I decided on letting all see my one tiny mini part jobscope. I'm preparing standardization for Bromine No. ASTM D1159 reagent. Titration of this reagent is troublesome, not only this, the whole portion of the standardization is in fact, troublesome. There are 2 steps to it. What I am showing is the 1st part, and I had already done the 2nd part the day earlier, which means, I am preparing for the next standardization. LOL... Prepare first then on that day, which is 3 mths later, I won't have to do that much.
(^_____^)v
Solution to be titrated, indicator is H2SO4(1+5). To titrate till it changes pale yellow.
Titrating till near end point & to add in starch indicator.
The Adding of Starch indicator, solution changes dark blueish.
End of titration, and the solution changes colorless.
My job, interesting right?? Hahaha... I have to deal with acids, chemicals, sometimes benzene...
(-_______-)
That's all. Ja-nai~
