Interpretation Introduction

Interpretation:

Fraction of ascorbic acid oxidized has to be calculated. Whether the concentration of ascorbic acid throughout the process is constant or not has to be stated.

Concept Introduction:

In analytical chemistry, coulometric titration is a method in which the titrating agent is produced in a solution by electrolysis. Amount of that substance is determined by measure of the quantity of electricity used to electrolyze that substance. For coulometric titration, no standard solution is needed.

Moles of electron flow in a coulometric titration are calculated by the equation as follows:

Moles of electron flow =(Electric current in amperes)(time in second)Faraday constant

We learned four factors (ARIO) for comparing the relative acidity of compounds. When two of these factors are in competition, the order of priority is the order in which these factors were covered ("atom" being the most important factor and "orbital" being the least important). However, we also mentioned that there are exceptions to this order of priority. Compare the two compounds and identify the exception. OH PK-4.75 SH PK-10.6 5. "Resonance" is more important than "atom" because the conjugate base of first compound is more stable than the second. "Atom" is more important than "resonance" because the conjugate base of first compound is more stable than the second. "Resonance" is more important than "atom" because the conjugate base of second compound is more stable than the first. "Atom" is more important than "resonance" because the conjugate base of second compound is more stable than the first.
