uber cool... hehe... 2day i did my 2nd chemistry practical... cool but kinda complicated as we reli need to be precise... very precise... hokay so... da prep of sodium hydroxide (NaOH) was a killer... da stupid alkali solution reli gave me a headache... to prep 250 cm3 of NaOH we were given solid sodium n distilled water... ok... to cut short (read: lazy wanna explain) after prep da solution... hav to titrate wit monobasic acid HX... question was to find concentration of da HX acid... *skippin all da nonsense* this was wat i did AFTER i finished da experiment... da balance NaOH solution i poured in phenolphthalein (da indicator) bout 1/5 of da phenolphthalein bottle... *its a lot...!* da whole solution turned, well, this...
this is wat u get when u pour TOO MUCH phenolphthalein into an alkali solution... u get ribena... or grape juice...?i couldnt resist take a pic of me goin mad... ok ok... tht sounds so wrong... hehehe...
