Homework Answers
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.

2. a. was The analysis of the complex formed between Cu(I) and 1,10-phenanthroline conducted using molecular spectroscopic method. The results showed that this complex has a molar absorptivity (8) of 7000 L cm'mol and maximum wavelength absorption (1) of 435 nm. Calculate the absorbance of a 6.77 x 10-6 M solution of the complex when measured in a 1.00 cm cell at wavelength of 435 nm. b....

Experiment 4: Identification of an unknown acid by titration Page 2 of 15 Background In this experiment, you will use both qualitative and quantitative properties to determine an unknown acid's identity and concentration. To do this analysis, you will perform a titration of your unknown acid sample-specifically a potentiometric titration where you use a pH meter and record pH values during the titration, combined with a visual titration using a color indi- cator...
