Aqueous solution chemistry of sulfur, selenium and tellurium

11 Aqueous solution chemistry of sulfur, selenium and tellurium 

Further, there is little difference in energy between the various oxidation state species of sulfur, a fact that is doubtless involved in the complicated oxoacid and oxoanion chemistry of sulfur. We have already discussed some aspects of the aqueous solution chemistry of the group 16 elements  

There is no cation chemistry in aqueous solution for the group 16 elements. The coordination to metal ions of oxoanions such as [804] and [8203] is well established (e.g. see equation 15.112). 

The following terms were introduced in this chapter. Do you know what they mean  

Greenwood and A. Earnshaw (1997) Chemistry of the Elements, 2nd edn, Butterworth-Heinemann, Oxford -Chapters 14-16 cover the chalcogens in detail. 

As we saw earlier in the chapter, the redox reactions between compounds of S in different oxidation states are often slow, and values of E° for half-reactions are invariably obtained from thermochemical information or estimated on the basis of observed chemistry. The data in Fig. 16.21 illustrate the relative redox properties of some S-, Se- and Te-containing species. Points to note are
