Ni2+ appears green in solution, so its concentration can be determined spectrophotometrically. A student measured the absorbances of several solutions of known Ni2+ concentration and created a plot of absorbance vs. [Ni2+]. The equation of the best-fit line for the calibration curve was determined to be y = 1.45x + 0.00162. What would be the concentration of a Ni2+ solution that has a measured absorbance of 0.560?

Since in absorbance v/s concentration plot, we plot the absorbance value in y axis and concentration…

Ni²⁺ appears green in solution, so its concentration can be determined spectrophotometrically. A student measured the absorbances of several solutions of known Ni²⁺ concentration and created a plot of absorbance vs. [Ni²⁺]. The equation of the best-fit line for the calibration curve was determined to be y = 1.45x + 0.00162. What would be the concentration of a Ni²⁺ solution that has a measured absorbance of 0.560?
