Chapter 3, Problem 3.24QAP
Interpretation Introduction

Interpretation:

The output voltage of an integrator 1, 3, 5, and 7 s after the start of integration needs to be plotted.

Concept introduction:

The output voltage can be calculated as follows:

v0=1RiC0tvidt

Here,

V0 = output voltage

Ri = input resistor

C = feedback capacitor

Vi = input voltage

T = time

The classical dissociation constant of propionic acid, C2H5CO2H, is 1.34 x10-5 moldm-3 at 250C and the limiting molar conductivities at zero concentration of hydrogen and propionate ions are 349.8 and 35.8 ohm-1 cm2 mol-1 respectively. Calculation of the resistivity of 0.100 M solution of propionic acid.
A standard solution was prepared containing 10.0 ppm of an analyte and 15.0 ppm of an internal standard. Analysis of the sample gave signals for the analyte and internal standard of 0.155 and 0.233 (arbitrary units), respectively. Sufficient internal standard was added to an unknown sample to make it 15.0 ppm in the internal standard. Analysis of the unknown sample yielded signals for the analyte and internal standard of 0.274 and 0.198, respectively. Calculate the concentration of analyte in the unknown sample.
Electrochemical detection is commonly used in combination capillary electrophoresis systems. This is a type of hydrodynamic voltammetry called flow injection, where it has been shown that ilim a U1/3, where U is the flow rate of the solution. Flow analysis of a urine sample at a thin-layer amperometric detector, with a flow-rate of 1.25mL/min, yielded a limiting current value of 1.6µA for its unknown uric acid content. A larger current of 2.4µA was observed for a sample containing 1 × 10-4 M uric acid and flowing at a rate of 0.9mL/min. Calculate the original concentration of uric acid in the sample
