Question: hi, i did this lab, from this website and I was wondering if anyone could come up with 3 sources of error, and they can't be human error. Thanks! You are saving me! Seeing as I am not allowed to post to the website :(, search on google liver lab with sand, and it is with a site called zerobio. Thanks!
I am in the same class and I am wondering the same thing...thanks!
What sources of error do you find?
Impurities in the sand
Uncontrolled environment (impurities in the air)
Sorry for not posting those before, I suppose that would have been more helpful..Thank you!
Your answers look good. :-)
Since some of the measurements are vague, that could be an error. Also, what about the concentration of the hydrochloric acid?
