Using the GRAPH IT function of MINEQL+, show changes in the dissolved concentrations of Pb and Cu as the pH changes from 4 to 8 at different partial pressure of CO2, ranging from 10-3.5 to 1.0 atm and corresponding to a logK of CO2(gas) range of 21.647 to 18.147.

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.
