HEY LETS CONTInue the discussion for the chem paper..

wat say?..

i just practised those sodium thisosulfate + potassium iodate questions..

am clear with them now.

--
can any one list out the experimental improvements?

for e.g use a burette/pipette instead of measuring cylinder

-repeat the experiments as average is more accurate

wat else?

any ideas?

@adi toxic - any more improvements (experimental)

these can be some

-use of colourimeter
-use of data logging (instead of timer)
-use of burette/pipette
-repeat and average
-clean the apparatus for no impurities
any more?

thats for physics..

insulation for chem..only exo. and endo. reactions..

for e.g

Devise an experiment to show that CaO + H2O is an exo. reaction


here..u add known amount of CaO to known volume of water. record the time and temperature using thermometer.stop the watch when temp. reaches a constant value.

here..the improvememnts can be.

-Use data logging
-Use insulation
