Question

What are the cations and anions for V2(CO3)3

Answer 1

Step-by-step explanation:

Cations are the species that hold a positive charge by losing electrons.

For example,
`Na^(+)`,
`V^(2+)`,
`Ca^(+)` etc are all cations.

Whereas anions are the species that hold a negative charge by gaining electrons.

For example,
`Cl^(-)`,
`CO^(2-)_(3)`,
`S^(2-)` are all anions.

Therefore, in the compound
`V_(2)(CO_(3))_(3)`, vanadium (
`V^(3+)`) is the cation and carbonate (
`CO^(2-)_(3)`) is the anion.

Answer 2

In chemistry, the nomenclature convention would be placing the cation first, followed by the anion. A cation is the positively charged ion, while an anion is the negatively charged ion. When these ions combine, their charges are 'cross-multiplied' and transformed to subscripts of the compound. Therefore, for the compound V₂(CO₃)₃, the cation is V³⁺ and the anion is CO₃²⁻.
