- What are the processes of concentrate samples analysis in Uv-visible spectroscopy? Please shortly answer at your own words(3-4 lines).In the spectrophotometer, why is there a need to measure a 'blank' sample? What will happen to the accuracy of your result if you measure the specimens without measuring a 'blank' trial? In the experiment, what liquid can be placed in the cuvette when measuring a 'blank' trial?The following image is a scheme for serial dilutions prepared for spectrophotometric analysis. If the stock solution concentration is 0.05 % (v/v) can you calculate the other tube’s concentrations in % v/v? I've used this with direct dilutions, how would I use this on serial dilutions?
