|
Students should be able to recall the names of the salts produced when phosphate rock is treated with nitric acid, sulfuric acid and phosphoric acid |
|
Recall the names of the salts produced when phosphate rock is treated with:
a) nitric acid
b) sulfuric acid
c) phosphoric acid |

|
|
Potassium chloride, potassium sulfate and phosphate rock are obtained by mining, but phosphate rock cannot be used directly as a fertiliser |
|
What process is used to extract rocks containing phosphate compounds from the earth? |
|
|
|
Phosphate rock is treated with nitric acid or sulfuric acid to produce soluble salts that can be used as fertilisers. |
|
How can rocks containing phosphate compounds be treated, in order to make soluble salts that can be used as fertilisers? |
