Question
Predict which will be more stable, $\left[\mathrm{CrO}_{4}\right]^{2-}$ or $\left[\mathrm{WO}_{4}\right]^{2-},$ and explain.
Step 1
In $\left[\mathrm{CrO}_{4}\right]^{2-}$, the chromium (Cr) is in the $6+$ oxidation state. Similarly, in $\left[\mathrm{WO}_{4}\right]^{2-}$, the tungsten (W) is also in the $6+$ oxidation state. Show more…
