Inorganic compounds activity coefficients

Explain in words how environmentally relevant inorganic salts affect the aqueous solubility of a (a) liquid, (b) solid, and (c) gaseous compound. Is it true that the effect is linearly related to the concentration of a given salt What is the magnitude of the effect of salt on the aqueous activity coefficient of organic compounds in typical seawater ... 

Consider the hydrolyses of methyl bromide (Reaction 1 in Table 13.2) and ethyl acetate (reaction 5 in Table 13.2) at 25°C and pH 7.0 in a contaminated groundwater containing 100 mM Cl and 1 mM Br. Assume that neither the pH nor the inorganic species concentrations change significantly during the reaction. Also assume that the activity coefficients of all species are 1. To what extent do the two compounds hydrolyze under these conditions ... 

While Eq. 9.4-13 will generally be used to calculate the fugacity of a species in a solid mixture, especially involving organic compounds, there are cases of true solid mixtures, especially involving metals and inorganic compounds. While vve defer considerations of such mixtures until Sec. 12.4, it is useful to note that the activity coefficient for a species in a true solid mixture, following Eq. 9.3-11, can be written as...
