Dear Histonetters!
For checking the endpoint of decalcification is traditionally used 5%
solution sodium oxalate or ammonium oxalate. Solubility in 100 ml water
for sodium oxalate 3,7v/w, but for ammonium oxalate forms accordingly
4,5 v/w. Thereby, we get the saturated solutions of these salts.
Why to this effect do not use potassium oxalate? His solubility in
100 ml water forms 26,4w/v. Can be therefore that in solution is got
too high concentration oxalate and this test not will so be sensitive?
Or this there is else some explanation?
Thank you.
