Manufacture of Sulphuric Acid
9.1 Manufacture of Sulphuric Acid
1. State uses of sulphuric acid in daily life. - lead acid batteries in automobiles and for home use - extraction of elements from ores - manufacturing of fertilizers
2.The following shows an incomplete flow chart of the Contact process.
a)
b)Chemical equation A. B. C. D.
3. Briefly explain the sources of sulphuric dioxide gas in atmosphere. -Sulphur dioxide is produced mainly from the combustion of fossil fuels that contain Sulphur , such as coal and oil.
4. State two effect of sulphuric dioxide on the environment. -Sulphur dioxide can cause acid rain that seriously affects ecosystems -can form secondary particles (sulphates) that cause haze and reduce visibility.
9.2 Manufacture of Ammonia and its salts
1. State uses of ammonia in daily life. -To make explosive chemicals such as TNT -In the rubber industry, ammonia is used to prevent the cogalation of latef
2. State physical properties of ammonia. -Ammonia,(NH₃) is a colourless and pinyentgas -It is less dense than air -It is highly soluble in water. NH₃ + H₂O NH₄OH
3.The diagram below show ]s a flow chart to prepare nitric acid and fertiliser Z from ammonia.
