"[FeSCN2+]eq is calculated using the formula: [FeSCN2+]eq = Aeq/Astd x [FeSCN2+]std where Aeq and Astd are the absorbance values for the equilibrium and standard sample respectively." I am confused about what Aeq and Astd mean. We did an experiment where we measured the absorption of this chemical formation and I got around 0.18. Is that one of the values?
Using the calibration curve y=0.146x+-0.368 find the the quantity of unknown protein that gives a measured absorbance of 0.918 when a blank has an absorbance of 0.138.
2. Two substances, A and B, have the same molar extinction coefficient at 260 nm: 1.80 x 10 dm³mol'cm'. At 340 nm A no longer absorbs, and for B EB = 6.22 x 103 dm³mol'cm'. A solution of the two has an absorbance of 0.215 at 340 nm and 0.850 at 260 nm in a 1 cm thick cell. Calculate the concentrations of A and B.
A sample of water from the North Sea was analysed by ion-chromatography and the sulfate concentration determined to be 2960 mg/L. A sample of formation water from a reservoir near Shetland was analysed by atomic emission spectroscopy and the strontium concentration determined to be 770 mg/L. If the Ksp value for strontium sulfate is 3.44x10- mol- L-2 predict whether precipitation should occur if 500 ml of the seawater is mixed with 500 ml of the formation water.

Atomic emission spectroscopy and the method of standard addition are used to determine the Na+ concentration and its uncertainty in an unknown sample. Increasing amounts of a 1.75 ug/mL standard Na+ solution are added to a series of volumetric flasks containing 15.00 mL of the unknown solution. The volumetric flasks are then diluted to a final volume of 200.0 mL. Atomic emission spectroscopy is then used to measure the emission intensity of each solution. Unknown volume Standard volume Final volume Emission (mL) (mL) (mL) intensity 15.00 0.00 200.0 351.0 15.00 5.00 200.0 494.0 15.00 10.00 200.0 642.0 15.00 15.00 200.0 807.0 15.00 20.00 200.0 948.0 Based on the data in the table, determine the original concentration of Nat and its uncertainty in the unknown sample.

An absorbance calibration curve for Zn was fitted to equation A = 0.913×`Zn, ppm`. Flask 1: To the first flask, a 1.00 mL aliquot of the unknown Zn solution was diluted to 100.0 mL in a volumetric flask; the absorption intensity from this sample was measured to be A = 0.204. Flask 2: To a second flask, a 1.00 mL aliquot of the unknown Zn sample and a 1.00 mL aliquot of 10.00 ppm Zn solution were added and diluted to 100.0 mL in a volumetric flask; the absorbance of this sample was measured to be A = 0.294. Calculate the % spike recovery for the analysis and report to the nearest whole number. Hint: A=mC of the type y=mx, so C=A/m %Spike=100%((Cspike-Coriginal)/Cadded)) Cadded can be found from C1 V1=Cadded V2.
