Post by: xD_aQt on February 26, 2010, 04:15:39 pm

What are some errors you might find while doing the experiments ?

inacurate measures and not performing the experiments tediously will cause errors to occur in your calculations. For example you may use incorrect washing techniques for the instruments you are going to use(Washing Burette with water instead of substance you are going to put in thereetc). You may not wash away adsorbed particles from your analyte properly... etc.

rinsing the equipment with the wrong solutions.
having a shifty scale
going overboard in titrations
precipation may contain other solutes other then the ones u wanteed
not boiling the solution enough

these were actually my errors in my prac i did :(
