A solution of [FeSCN]2+ in a 1.0 cm cuvette has an absorbance of 0.371 at 447 nm. If the molar absorption coefficient (E) is 4400 [L / (molxcm)], what is the concentration of [FeSCN]2+ ? (enter the answer in decimal form, not scientific notation, with three significant figures at the end) M[FeSCN]2+ AJ

[FeSCN 2 +]eq = X [FeSCN 2 +]std Knowing the [FeSCN 2 +]eq allows you to determine the concentrations of the other two ions at equilibrium. For each mole of FeSCN 2 + ions produced, one less mole of Fe 3 + ions will be found in the solution (see the 1:1 ratio of coefficients in the equation on the previous page).

The molar absorptivity of the FeSCN^2+ complex ion is 4700M^-1*cm^-1 at a wavelength of 450nm. using a 1-cm sample tube, you Your solution’s ready to go! Our expert help has broken down your problem into an easy-to-learn solution you can count on.

Answer to Fe3+(aq) + SCN-(aq) → FeSCN2+(aq) Calculate the. Identify the products and reactants in the chemical reaction equation and realize that the equilibrium constant (Kc) for the reaction is calculated using the formula where the concentrations of the products are divided by the concentrations of the reactants, with each raised to their respective stoichiometric coefficients.

Calculate the concentration (in M) of [FeSCN]2+ (aq) in a standard solution prepared by combining 10.0 mL of 0.200 M Fe(NO3)3(aq) and 2.50 mL of 0.00200M KSCN(aq) and diluting to a total volume of 25.00 mL with deionized water. Assume that all of the SCN- reacts with Fe3+ to produce [FeSCN]2+.

For the solutions that you will prepare in Step 2 of Part I below, calculate the [FeSCN 2+]. Presume that all of the SCN – ions react. In Part I of the experiment, mol of SCN – = mol of FeSCN 2+. Thus, the calculation of [FeSCN 2+] is: mol FeSCN 2+ ÷ L of total solution. Record these values in the table below.

Part 2. Calculating Equilibrium Constants for Iron(III) Solutions Using your calibration curve, find the [FeSCN2+]eq concentrations from the absorbance values you read. Report Table 7.3: [FeSCN 2 +] eq concentrations in Part 2 Table view I List vie Data and calculation of equilibrium equilibrium concentration (− 0.1 pts) Incorrect.
