Answer
Brief Explanations:
According to solubility rules:
- Sulfates ($\ce{SO^{2-}{4}}$) are generally soluble, but $\ce{BaSO{4}}$ is insoluble.
- Carbonates ($\ce{CO^{2-}{3}}$) are generally insoluble except those with Group 1 metals and $\ce{NH^{+}{4}}$. So $\ce{MgCO_{3}}$ is insoluble.
- Fluorides ($\ce{F^{-}}$): $\ce{SrF_{2}}$ is insoluble.
- Sulfides ($\ce{S^{2-}}$): $( \ce{NH_{4}}){2}S$ is soluble (sulfides of $\ce{NH^{+}{4}}$ are soluble).
- Iodides ($\ce{I^{-}}$): $\ce{MgI_{2}}$ is soluble (iodides are generally soluble except with $\ce{Ag^{+}}$, $\ce{Pb^{2+}}$, $\ce{Hg^{2+}_{2}}$).
- Phosphates ($\ce{PO^{3-}{4}}$): $\ce{Li{3}PO_{4}}$ is soluble (phosphates of Group 1 metals are soluble).
Answer:
$\ce{SrF_{2}}$, $\ce{BaSO_{4}}$, $\ce{MgCO_{3}}$
