Protein ABC is a heme-containing protein responsible in electron transfer in microalgae. The target protein was extracted using ammonium sulfate fractional precipitation and quantified using Bradford assay. A set of solutions with increasing concentration was prepared using 15.00 mg/mL analogous protein standard [refer to succeeding table]. Each solution was treated with 80 μL of Bradford reagent and diluted to 1.500mL. The absorbance at 595 nm of each solution was obtained and presented below.

An 80% exhausted cation exchanger softened 20320 litres of water. 60 ml of this water sample consumed 12.4 ml of 0.01 M EDTA solution using EBT indicator. How many litres of water of hardness of 450 ppm as equivalents of CaCO3 can be treated by the regenerated cation exchanger? What is the volume of hydrochloric acid of specific gravity of 1.19 g.ml1 required for the complete regeneration of the cation exchanger?
Chloroform is an internal standard in the determination of the pesticide DDT in a polarographic analysis in which each compound is reduced at an electrode surface. A mixture containing 0.500 mM chloroform and 0.800 mM DDT gave signals of 15.3 µA for chloroform and 10.1 µA for DDT. An unknown solution (10.00 mL) containing DDT was placed in a 100-ml volumetric flask and 10.2 ul of chloroform (MW = 119.39, density = 1.484 g/mL) were added. After dilution to the mark with solvent, polarographic signals of 29.4 and 8.7 µA were observed for the chloroform and DDT, respectively. Find the concentration of DDT in the unknown.
A dual beam UV-visible spectroscopy was used to determine the levels of Fe(II) in the run-off water of a local mine using the ferrozine assay (i) During a check of the instrument a step-like feature at 360 nm was observed in spectrum of the standard. Suggest what may give rise to this with reference to the instrument configuration and comment on how it may be remedied. (ii) The molar absorptivity of the [Fe(Ferrozine)3]2+ complex is 27900 cm−1 M−1 at 562 nm in aqueous solution (pH 5.5). If the EU maximum contaminant level for Fe is 200 ug /L and the contract required detection limit is 100 ug/L, comment on the suitability of the assay for the detection of iron. (iii) Determine the sample range, in terms of concentration and ppm, of Fe(II) that can be confidently analysed by UV-visible spectroscopy using a 1 cm cuvette. Explain with reference to an appropriate equation and solution phenomena, the origin of the limitations that define this range
In order to improve the peptide separation by using a HPLC system, trifluoroacetic acid acts as mobile-phase modifier was added during the preparation of mobile phase. The preparation was performed by a postgraduate student as following:“2.851 g trifluoroacetic acid (MW: 114.02 g/mol) was made up to 500 cm3 in a graduated flask. To this solution, 50 cm3 of ethanol was added, and after mixing the mobile phase was placed in the solvent reservoir and pumping was commenced at 1.5 cm3 min-1.”Based on the given preparation procedure, identify THREE mistakes that were made.

A Dubosq colorimeter consists of a cell of fixed path length and a cell of variable path length. By adjusting the length of the latter until the transmission through the two cells is the same. the concentration of the second solution can be inferred from that of the former. Suppose that a plantdye of concentration 25 μg dm-3 is added to the fixed cell. the length of which is 1.55 em. Then a solution of the same dye. but of unknown concentration. is added to the second cel l. It is found that the same t ransmittance is obtained when the length of the second cel l is adjusted to 1.18 em. What is the concentration of the second solution?
Estimate the concentration of nitrate in the aquarium water. Aquarium water was diluted from 1 mL to 100 mL, and the final solution contains the same 10 ppm of internal standard IO2 4 as in the standard mixture. For an estimate, use peak height instead of peak area. There is no need to use normalized peak area 5 peak area/migration time because migration times are nearly the same in both electropherograms.
