As one does every 20 years or so, I can across a HUGE bag of something
called 'Phosphoric Acid' which I obviously bought for some use, but what was
it used for?

Dissolving human bones and teeth after you have turned the rest of
their bodies into meat pies.

When I first saw the bag the words 'growmore' came to mind, but bearing in
mind the reliability of my memory it could be anything!

Growmore is an ordinary NPK (nitrogen-phosphorus-potassium) fertiliser.
Phosphoric acid is just a source of phosphorus.
