Step by step
Solved in 2 steps
- When using a Gran plot to determine the equivalence point, we must use the data after the equivalence point. Group of answer choices True Falsewhy the answer here is E, not D? + what is the difference between equivalent point and ending point?Which of the curves seems to have the shortest vertical line around its equivalence point? Explain why. (If you suspect that your data are inaccurate, explain which curve you think should have been most vertical and why.)
- From the data, give 3 potentiometric plots. Show the equivalence point in the 3 graphs.Can you please explain #7 I really do get confuse when they say to look for m and I don't know what to useI 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!!!!!!
- Using the following data: A (Chloroacetic acid) ClCH2COOH system, pKa = 2.472, Ca = 0.025M. Construct the plot of the master variable (Log C versus pH).Derive a general expression that shows pH dependence of the distributioncoefficient defined in (2-20) for a weak acid between a fermentation broth and an organic solvent.I need help on figuring out which are the four data points that can be considered outliers, below is my graph following the intructions but, not I dont know which points are outliners.
