Question

omplex potassium trioxalatoaluminate . is this complex stable ? why?​

Answer 1

Answer:

Explanation:

Potassium ferrioxalate, also known as potassium trisoxalatoferrate or potassium tris(oxalato)ferrateis a chemical compound with the formula K

3[Fe(C

2O

4)

3]. It often occurs as the trihydrate K

3[Fe(C

2O

4)

3]·3H2O. Both are crystalline compounds, lime green in colour

The compound is a salt consisting of ferrioxalate anions, [Fe(C

2O

4)

3]3−, and potassium cations K+. The anion is a transition metal complex consisting of an iron atom in the +3 oxidation state and three bidentate oxalate ions C

2O2−

4 anions acting as ligands. Potassium acts as a counterion, balancing the −3 charge of the complex. In solution, the salt dissociates to give the ferrioxalate anion, [Fe(C

2O

4)

3]3−, which appears fluorescent green in color.
