Acid Base Titration: Calculating Absolute Error

Click For Summary
The discussion revolves around calculating the absolute error of acidic concentration in a lab report. The initial query seeks guidance on this calculation, prompting a request for more details about the measurements and formulas used. The user expresses frustration over receiving lower grades for minor discrepancies in measurements, specifically noting that even a 0.1 mL difference significantly impacts their report grade. This concern leads to a debate about the fairness of grading based on small measurement errors, with some participants suggesting that achieving accuracy to within 0.1 mL is reasonable in titration experiments. The conversation emphasizes the importance of precision in scientific measurements while also highlighting the emotional impact of grading practices on students.

i am doing my lab report and i just want to know how to calculate the absolute error of the acidic concentration and thank you.

Hi queenstudy! :smile:

Can you give us a little more to work with...?
What did you measure?
Which formula(s) did you use to calculate the acidic concentration from your measurements?
 
thank you serena but fixed my problem , but i just want to know something , why if i have a value different from the professor for every 0.1 ml my report grade decreases more and more its really unfair
 
Umm... how is this unfair?
 
if makes a huge difference , like 1 to 2 ml okay but 0.5ml will make youfail in the report i don't know is it a bit harsh?
 
I'm sorry about your grade. :frown:

But I believe you can do a titration accurately to 1 drop, which is about 0.03 mL.
Shouldn't an accuracy of 0.1 mL be achievable if you work carefully?
 
i really don't know its okay i love to learn my mistakes but also be fair hehehe thank you very much serena
