Part E

Write a balanced net ionic equation for dissolution reaction of BaCO3.

Express your answer as a chemical equation. Identify all of the phases in your answer.

ZnS BaCO3 Fe(OH)3 BaSO4

Explanation / 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)
