Fertilisers Flashcards
What si the catalyst for the ostwald process
platinum
Name the industrial process used to manufacture ammonia
The haber process
Name the industrial process used to manufacture nitric acid
The ostwald process
What is the catalyst used in the haber process
iron
Suggest why fertilisers must be soluble in water
So they cna be absorbed into the root of the plant
What is the test for ammonia
test would trurn pH paper blue
What is the test for nitric acid
Test would tunr pH paper red
State why ammonium nitrate is widely used as a fertiliser
ammonium nitrate supplies nitrogen to the soil which is essential for healthy plant growth
explain why a high temperature is not used in the haber process
The ammonia will break back down to nitrogen and hydrogen
Explain why a low temperature is not used in the haber process
reactipn will happen to slow
What step is taken by manufacturers to ensure all reactants eventually form products
Unreacted gases can be recycled
What is the starting material in the production of nitric acid
Platinum
