Monoammonium Phosphate OTC
I see at this time of year (in the US), toy retailers are selling crystal growing kits as a STEM activity. The salt used for growing the crystals is
monoammonium phosphate, (NH4)(H2PO4). The kits range from about $8 to $15 in price, with the $15 ones containing as much half a pound of this
chemical.
Seems this should be a convenient source for someone looking for a phosphate salt. It can also be decomposed fairly readily to phosphoric acid (above
200 degrees C), though this would likely require distillation apparatus and a fume hood.
