Hello!
I've got an old bag (yes, bag) of sodium tripolyphosphate. I've have little or no use of this salt... However I do have use of various phosporic
acids.
Question: Is there anyone in this forum who knows a way to hydrolyze this trimeric phosphoric acid salt into its monomer acid or its salt (I assume
the acid can be made by simple protonation by sulphuric acid from the corresponding acid salt)?
Thanks in advance!

What does it mean when the forum information about this thread shows "-1" replies?
Does it mean that my original post sucked, or what?

I suppose you could add an appropriate amount of calcium chloride to the solution, then filter off the ppt of insoluble calcium phosphates, then wash
the ppt and react that with H2SO4 to ppt calcium sulfate and leave phosphoric acid in solution. Of course, this is impractical unless you have a lot
of sulfuric acid.

Furch that is a good one! I think that makes sense and propose (with your
permission) to the board administration that it become standard policy.
