Contrast two voltage waveforms for controlled potential electrolysis and the resulting current vs voltage plots that result. what are the conditions that produce the shapes of the curves and what analytical information can be extracted from each? model the titration of carbonic acid, a diprotic weak acid with pka values of 6.3 and 10.3, with naoh. what are the prominent features of thistitration curve and how can this information be used to extract analytically useful information about the sample?

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.

c. 4.54 x 10–12 j happens to be correct
