Last week, I did titration of Zn with EDTA experiment. I used calmigte as the indictor. The endpoint of this titration is supposed to be blue. The color change go from wine-red to violet to Blue. I did a mistake by stopping the titration at the violet col...

why do we use different instrument to make absorbance and fluorescence measurments?

In fluorescence, why do we have to preapre a calibaration curve for every compound in our sample?

I meant to say "Is there anyway to estimate how many mL I am away from the blue endpoint. Thanks
