A 0.0712-g sample of a purified organic acid was dissolved in an alcohol-water mixture and titrated with coulometrically generated hydroxide ions. With a current of 0.0392 A, 241 s was required to reach aphenolphthalein end point. Calculate the equivalent mass of the acid.
The following statements are true for Amperostatic Cuolometric Methods of analysis except - in constant current system, the potential of the cell will vary in time as analyte is consumed cuolometric titrations can be performed at constant current to generate a known quantity of titrant electrochemically a second electrode is no longer needed to detect endpoint of the analysis can be used for acid/base, complexometric and redox titrations The following are true about redox reactions except: * it involves transfer of electrons or charged particles the reaction is performed by bringing the oxidant and the reductant into direct contact in a container the reaction is carried out in an electrochemical cell in which the reactants do not come into contact. an anode is where reduction takes place The following are excitation signals used for voltammetry except-* linear scan differential pulse square wave triangular wavelength quant
