Question

Write the chemical name for the ionic compound and mention the molecular weight

${\mathrm{FeC}}_2{\mathrm{O}}_4$

Answer 1

Ionic Compound

• The ionic compounds contain ions and are held together by the attractive forces among the oppositely charged ions.
• In this compound, ions are held together by an ionic bond
• In these compounds, one ion gains an electron(anion) and another one gives the electron(cation).

${\mathrm{FeC}}_2{\mathrm{O}}_4$

• The chemical name of ${\mathrm{FeC}}_2{\mathrm{O}}_4$ is Ferrous oxalate. its IUPAC name is Iron(II) oxalate.
• The dihydrate of ferrous oxalate is a coordination polymer.

Molecular weight:

• Mass of $\mathrm{Fe}=55.8\mathrm{g}$
• Mass of $\mathrm{C}=12\mathrm{g}$
• Mass of $\mathrm{O}=16\mathrm{g}$
• Mass of ${\mathrm{FeC}}_2{\mathrm{O}}_4=55.8+(2\times 12)+(4\times 16)\mathrm{g}=143.8\mathrm{g}$ = 55.8 + (2 x 12) + (4 x 16) = 143.8 g
