ZIMSEC O Level Combined Science Notes: Uses of sulphuric acid
- Most of the sulphuric acid produced at Zimphos is used to
- make fertilizers (mostly superphoshate)
- Some of the sulphiric acid is used to manufacture aluminum sulphate
- Which in turn is used as a flocculent in water purification processes
- Bauxite from Mutare is dissolved into sulphuric acid
- The word equation for the process is:
- \text{aluminum oxide+sulphuric acid}\rightarrow\text{aluminium sulphate+water}
- Sulphuric acid also has other uses including:
- extraction of metals
- cleaning metals before plating
- It is also used in:
- the manufacture of textiles
- electrolyte in car batteries
- paper making
- manufacture of detergents
- As a drying agent/desiccate because it absorbs water
- In the manufacture of plastics
- The manufacture of paints
