ZnS BaCO3 Fe(OH)3 BaSO4Explanation / Answer
A)
ZnS --> if H+ is present, then more HS- forms, which shifts toward MORE solubility
BaCO3 --> addition of H+ will make HCO3- ot increae, so solubilty increases
Fe(OH)3 --> H+ will react with OH- so there will be an increase in solubility
BaSO4 ---> H+ + SO4-2 --< HSO4 forms, so there is also icnrease in solubility
B)
ZnS(s) <--> Zn2+(aq) + S2-(aq)
C)
Fe(OH)3(s) <--> Fe3+(aq) + 3OH-(aq)
D)
BaSO4(s) <--> Ba2+(aq) + SO4-2(aq)
E)
BaCO3(s) <--> Ba2+(aq) + CO3-2(aq)
