Chapter 5, Problem 5.30P

(a)

Interpretation Introduction

Interpretation:

The response factor for the analyte has to be calculated.

Concept Introduction:

Response factor,

In chromatography, a response factor is well-defined as the proportion between the concentration of a compound being analyzed and the response of the detector to that compound.

Answer to Problem 5.30P

The response factor for the analyte is 0.1684 .

Explanation of Solution

Given,

In chromatographic analysis, a solution has an analyte concentration of 3.47mM and a standard concentration of 1.72mM gave peak areas 3473and10222 respectively. Then addition of 1.00mLof8.47mM standard concentration was added to 5.00mL of unknown X and then the mixture was diluted to 10.0mL . The peaks gave form the solution are 5428and4431 for X and S

signal from analyteconcentrationofanalyte=F(signal from standardconcentrationofstandard)

AX[X]=F(AS[S])

3473[3.47mM]=F(10222[1.72mM])F=3473[3.47mM]×([1.72mM]10222)F=0.1684

Conclusion

The response factor for the analyte was calculated as 0.1684 .

(b)

Interpretation Introduction

Interpretation:

The concentration of S(mM) in 10.0mLmixture has to be calculated.

Answer to Problem 5.30P

The concentration of S=0.847mM .

Explanation of Solution

Given,

In chromatographic analysis, a solution has an analyte concentration of 3.47mM and a standard concentration of 1.72mM gave peak areas 3473and10222 respectively. Then addition of 1.00mLof8.47mM standard concentration was added to 5.00mL of unknown X and then the mixture was diluted to 10.0mL . The peaks gave form the solution are 5428and4431 for X and S

[S]=initialconcentration×dilutionfactor

[S]=(8.47mM)(1.00mL10.0mL)

[S]=0.847mM

Conclusion

The concentration of S(mM) in 10.0mLmixture was calculated as 0.847mM .

Answer to Problem 5.30P

The concentration of [X]=6.16mM .

Explanation of Solution

Given,

In chromatographic analysis, a solution has an analyte concentration of 3.47mM and a standard concentration of 1.72mM gave peak areas 3473and10222 respectively. Then addition of 1.00mLof8.47mM standard concentration was added to 5.00mL of unknown X and then the mixture was diluted to 10.0mL . The peaks gave form the solution are 5428and4431 for X and S

signal from analyteconcentrationofanalyte=F(signal from standardconcentrationofstandard)

AX[X]=F(AS[S])

5428[X]=0.1684(4431[0.847mM])[X]=54280.1684×([0.847mM]4431)[X]=6.16mM

Conclusion

The concentration of X(mM) in 10.0mLmixture was calculated as 6.16mM .

Interpretation Introduction

Interpretation:

The concentration of X(mM) in the original unknown has to be calculated.

Answer to Problem 5.30P

The original concentration of [X]in the unknown is 12.3mM.

Explanation of Solution

Given,

In chromatographic analysis, a solution has an analyte concentration of 3.47mM and a standard concentration of 1.72mM gave peak areas 3473and10222 respectively. Then addition of 1.00mLof8.47mM standard concentration was added to 5.00mL of unknown X and then the mixture was diluted to 10.0mL . The peaks gave form the solution are 5428and4431 for X and S

The original concentration of [X] was two times greater than the diluted concentration

Diluted concentration is

[X]=6.16mMoriginal concentration=2[X]=2[6.16mM]=12.3mM

Conclusion

The original concentration of X(mM) in the unknown was calculated as 12.3 mM .
