Enough detail in answer please
Compare the results obtained on the analysis of magnesium by A.A. and titrimetry(using EDTA) and account for any differences between the two. Which method is more accurate and why? Which method could be automated?

Average titre =5.23cm^3
Flame AAS reading for same sample = 0.141

Magnesium concentration = 0.495mg/L

Answer #1

Titrimetry(using EDTA) method is more accurate than Flame AAS (Atomic Absorption Spectroscopy).

Explanation: The results obtained by titration are always accurate than the results obtained by instrumentation because the titration is performed by humans with precise care, whereas the flame AAS method doesn't involve the precision of analysis.
