Identify the correct formula for the complex named "Potassium trioxalatoaluminate(III)". — Coordination Compounds Chemistry Question

💡 Solution & Explanation

$Al$ is +3. Three $C_2O_4^{2-}$ give -6. Net charge of the sphere is $3 - 6 = -3$. To balance, three $K^+$ ions are needed. Formula is $K_3[Al(C_2O_4)_3]$ [16, 17].
