I need to know: 1. moles FeNCS2+ at equilibrium (10mL) (mol) 2. moles Fe3+, reacted (mol) 3. moles Fe3+, equilibrium (mol) 4. [Fe3+] equilibrium,
I did an experiment: Molar concentration of Fe (NO3)3=.002
Molar concentration of NaSCN= .002
On my 1st trial:
Volume of Fe(NO3)3 = 5 mL
Moles of Fe3+, initial (mol) = 1 x 10-5
Volume of NaSCN (mL)= 1 mL
Moles of SCN-,initial (mol)= 2 x 10-6
Absorbance was .08
Now trying to find Calculation of Kc
I already found [FeNCS2+] equilibrium, from calibration curve (mol/L)= 2.25 x 10-5
Now I need to know:
1. moles FeNCS2+ at equilibrium (10mL) (mol)
2. moles Fe3+, reacted (mol)
3. moles Fe3+, equilibrium (mol)
4. [Fe3+] equilibrium, unreacted, 10 mL (mol/L)
5. moles SCN-, reacted (mol)
6. Moles SCN-, equilibrium (mol)
7. [SCN-] equilibrium (unreacted) 10 mL (mol/L)
Feel free to just give me the formula to find these. Or to charge me 2 or 3 questions if I asked too much. Thank you!!!!!!
