Acid Base Titration: Calculating Absolute Error

Click For Summary
SUMMARY

This discussion focuses on calculating the absolute error in acid-base titration, specifically regarding the accuracy of measurements and their impact on lab report grades. Participants emphasize the importance of precision, noting that even a 0.1 mL discrepancy can significantly affect results. The conversation highlights that achieving an accuracy of 0.1 mL is feasible with careful technique, and it addresses concerns about grading fairness based on minor measurement differences.

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
