what is the anion and cation of Na2CrO4
To find the anion and cation of Na2CrO4, we need to understand the composition of the compound.
Na2CrO4 consists of sodium ions (Na+) and the chromate ion (CrO4^2-).
In this compound, the sodium ions (Na+) act as the cations, as they carry a positive charge. The chromate ion (CrO4^2-) acts as the anion, as it carries a negative charge.
Therefore, the cation in Na2CrO4 is Na+ (sodium ion), and the anion is CrO4^2- (chromate ion).
