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)
2·2H
2O with
Potassium oxalate monohydrate K
2(COO)
2·H
2O and
Aluminium hydroxide Al(OH)
3 to form
Potassium Trioxalatoaluminate trihydrate K
3[Al(C
2O
4)
3]·3H
2O
The equation therefore should look like this?
(COOH)
2·2H
2O + K
2(COO)
2·H
2O + 2Al(OH)
3 
K
3[Al(C
2O
4)
3]·3H
2O + H
2O
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 H
2O has been eliminated, is this right as H
2O is in excess?
3(COOH)
2 + 3K
2(COO)
2 
2K
3[Al(C
2O
4)
3] + 6H
