This is not the yellowish poison itself — that word is . Phosphoric is the describing word: of or containing . Students meet it most in phosphoric acid, the common compound in tiny amounts in many cola drinks, and in much larger amounts in rust and plant food. Chemists also contrast phosphoric with phosphorous (that extra o), which is a different, more technical pairing; for most , phosphoric means “the adjective, especially in phosphoric acid”. Formal, textbook, lab-label language — not a word you toss into a story.
