I can't believe I completed my karangan (a composition in Bahasa) with good feelings. Writing a karangan is such a drag, man. I would usually feel so lazy finishing it, but this time it was different. I was like happy doing it. Heh...something's wrong with me. It could've been the "happy" music playing on the radio. I finished my karangan!!!

Something happened during our Kimia (Chemistry) class today. Our experiments usually fail. But that's not what happened...although it did (what the?). Were were doing titration of NaOH (Sodium Hydroxide) and HNO3 (Nitric Acid, I think) today. One thing that went wrong was when we added phenolphtalein into NaOH (some sort of an indicator -- turns red-pinkish in alkali) it automatically turned from pink to clear. It wasn't supposed to do that. It's supposed to turn clear after we added HNO3. The "clearness" indicated a neutral pH after a right amount of HNO3 was added to NaOH. So we added more phenolphtalein. Same thing happened.

We were originally using 2 dcm-1 of NaOH, but we changed it to 1 dcm-1. We thought maybe the pH was too strong or something. But we ran out of it. We were supposed to form crystals. But we just went with the experiment anyways. When we put NaOH + HNO3 together and boiled it, it was like BOILING madly. The solution was like "shot" out of the dish with pop sounds. We the fire turned off. My teacher came with the conclusion that the solution was over acidic. Failure. *sigh*

Had my first glimpse of Potassium Manganate (I think that's how you spell it). It's like purple when you put it in water. So cool. Sakai. Anyways, I think I'd better stop talking about chemicals and stuff cuz maybe you guys can't understand it...or if you do understand it, you won't bother trying to understand it. Wait. I've got myself confused. Heh.
