Recall the names of salts made when phosphate rock reacts with nitric acid, sulfuric acid and phosphoric acid. (Chemistry only)

In the subtopic Production and uses of NPK fertilisers, this learning objective focuses on recall the names of salts made when phosphate rock reacts with nitric acid, sulfuric acid and phosphoric acid. (Chemistry only). Within The Haber process and the use of NPK fertilisers, students should explain this idea in the exact curriculum context rather than as an isolated fact. Approved keywords for this objective include chemistry only, salt, nitric acid, sulfuric acid, and phosphoric acid. phosphate rock means a naturally occurring mineral that is mined and treated to produce soluble salts for fertilisers. Avoid students often confuse the names of salts produced from phosphate rock reactions with different acids; instead to fix this, students should memorize the specific salts formed from each acid: for nitric acid, it's calcium nitrate; for sulfuric acid, it's calcium sulfate; and for phosphoric acid, it's calcium phosphate. For exam answers, create flashcards for the salts produced when phosphate rock reacts with nitric acid, sulfuric acid, and phosphoric acid.
