How do i get tricalcium phophate out of my flask?


The title says it all.
I have just distilled some nitric acid from phosphoric acid and calcium nitrate. So now my flask is filled with insoluble calcium phophate. Any ideas?

Strong acid will convert it into calcium hydrogen (or dihydrogen) phosphate, which is soluble.

Citric acid might also do the trick.
Sulphuric- the obvious cheap strong acid- will make gypsum which is insoluble.

Or some EDTA if you've got some.

Maybe with help of ultrasounds (sonication) and a solvent you could get self crushing into dust.

This would anyway help your acid to work.
