today was the start of my first experiment in lab
it was calculation for the start and till the end
how exciting -_-!
what i did was dilute the chemicals till different conc.
(and again i couldn't calculate the conc. thank god, the senior helped me,haha)
then after a while we used the spectrophotometer to measure the absorbance
and then a curve was plotted
they say we need to use curve to estimate some values, which will be useful in a few days time
don't quite understand thought
but ya this is what i did today
and in the night which is about now
we went to wash our clothes
it's 3RMB per wash
we start the machine and leave it there and most likely, we'll go back down to check later haha
don't think anyone would steal our clothes.
yup that's all
hopefully tomorrow i'll get to do better stuff
see ya!!!
