ferric oxalate

[Juan Miguel Jusdado <jusdado@teleline.es>]

Thanks to all to answer.    
1. - I don't have magnetic mixer.    
2. - the ferric oxalato that I am mixing is of yellow color.    
3. - 2 days mixing and alone there is yellow mud in the bottom.    
4. - if he/she ended up mixing completely, I believe that he/she would 
have color yellow ocher, never clear and transparent.    
5. - the formula that figures in the bottle is:  
*
   Fe(CoO)_2 **2H_2 O *
   
6. - I also have oxalato ferric amónico. The formula that figures in the 
bottle is:  
   * (C_2 O_4 )_3 Fe(NH_4 )_3 4H_2 O*
   
7. - I am preparing this mixture for kalitípia processes.    
My question:    
Could it substitute the ferric oxalato for the oxalato ferric amónico 
for the same purpose?.
