Titration again...

As usual, i m unusually excited today because there is chemistry practical... n as u all might haf guessed, its titration!! this week's one is more exciting...

Last week, we used acids that we already noe the concentration which is already prepared by the lab tech... but today, i made a standard solution myself!!! so excited.. then use it to titrate against sodium hydroxide which we dunno the concentration... the indicator we used was phenolphthalein... wah... was so excited when it turned from colourless to pink in colour!! wah... some more its add the deciding drop of sodium hydroxide from the burette... so excited... the colour is pale pink... pale until cannot pale... but still can see its pink... then.. today also better than last week... cause this time my readings were within 0.1 cm cube of each other... =)))

Neway... basically.. thats abt it today... still kinda excited... lolx...
