Product description
28-2. A weighed portion of an alloy of mass m g was dissolved and, after appropriate treatment, the Cu2 + ions were titrated with the EDTA spectrophotometric method at λeff. = 620 nm. Build the titration curve and calculate the mass fraction (%) of copper in the alloy according to the following data:
m = 0.9968 Concat complexone mol / l 0.1014
Opt. solution density after adding EDTA, ml:
1 2 3 4 5 6
0.185 0.28 0.385 0.485 0.525 0.525
