Plzzz ,need help for chemistry p.61 now

[Beedo]

What are the possible sources of error ?
this question usually come in every test question 3 or 4 and I can,t answer it.
also what improvements can be done to reduce this error?
plzzzzz , need help as fast as possible because I,m leaving home in 15 min. & going to the exam centre

 

[Beedo]

for example in N03 page 7 no3 d-ii& iii

 

[mr0fisher]

1) plotting error
2) recording error
ANY OTHER QUESTIONS

Possible source of error- inaccuracy due to use of measuring cylinder, heat loss due to poor insulation.
Improvements- use burette, insulator, repeat and find average.

THATS IF THEY USE A MEASURING cylinder

 

[Beedo]

what are the usual plotting errors?
Thanks

I know that and that's why I stated its due to measuring cylinder. for a graph u can say plotting, recording, measuring, timing errors.

 

[thats_me]

for example in N03 page 7 no3 d-ii& iii

its recording error and inaccurate as using measuring cylinder improve: by using burette and digital stop watch for time...
