Draw a calibration curve using the data set given below. Show and explain LOD and LOQ. Determine the dynamic linear range by examining the linearity of the absorbance measurements against Metal atoms concentration. Also Explain calibration methods. (hint: there are there types of methods. These are internal, external and standard addition methods) Metal, ppm Absorbance 0.220 0.044 0.440 0.090 1.100 0.228 2.200 0.465 4.400 0.932 6.600 1.187

As the pH changes, how will the absorbance change at the wavelength of the isosbestic point?

.Express the following absorbances in terms of percent transmittance a) 0.0356 b) 0.379 0.167 c) 0.485

A student carries out the equilibrium constant experiment following a similar procedure used in the LearnSmart Lab simulator. In the first part of the experiment, there is a contaminant which causes absorbance values to read higher than they should for the thiocyanatoiron(III) complex. The resulting Beer's law plot has a slope that is larger than it would be if the contaminant was not present. This results in a Beer's Law plot with a slope that is larger than it would be if the contaminant were not present. If the same contaminant was not present when the student carries out the second part of the experiment, how will the student's results be affected? The molarities of thiocyanatoiron(III) ion would calculate higher and the calculated K. values would calculate higher. The molarities of thiocyanatoiron(III) ion would calculate lower and the calculated K. values would calculate lower. The molarities of thiocyanatoiron(III) ion would calculate higher and the calculated K. values would…

Which structure does this IR belong to and why?

A student calibrated the mini-spectrophotometer with a blank solution, and then went to check their solution. They got a fingerprint on the cuvette while filling it. Because of this, the expected reading for the absorbance would be too high which would cause the calculated value of K, to be too high

help please answer in text form with proper workings and explanation for each and every part and steps with concept and introduction no AI no copy paste remember answer must be in proper format with all working

Absorbance has no units. Please derive the units of the molar extinction coefficient ε.

Give answer all questions with explanation please
