Equation for Prep. of Potassium Trioxalatoaluminate trihydrate
« on: December 03, 2015, 02:30:53 PM »
Hello fellow Chemists!

I felt a bit flummoxed when trying to attempt to find a correct balanced equation for this substance. My experiment involved mixing oxalic acid dihydrate (COOH)2·2H2O with Potassium oxalate monohydrate K2(COO)2·H2O and Aluminium hydroxide Al(OH)3 to form Potassium Trioxalatoaluminate trihydrate K3[Al(C2O4)3]·3H2O

The equation therefore should look like this?

(COOH)2·2H2O + K2(COO)2·H2O + 2Al(OH)3 :rarrow: K3[Al(C2O4)3]·3H2O + H2O

I need help balancing the above. Any help would be much appreciated!  :)

Note: I was able to balance this equation as shown below but obviously H2O has been eliminated, is this right as H2O is in excess?

3(COOH)2 + 3K2(COO)2  :rarrow: 2K3[Al(C2O4)3] + 6H2

Hard to say where is the problem, it balances nicely.

I would start with K.
