Sulfur and Sulfuric acid
- Sulfur
- Sources
- Mining
- sulphide ores
- Natural gas and petroleum
- Mining
- Uses
- manufacturing sulfuric acid
- make rubber tyres flexible (vulcanising)
- making dyes
- manufacturing sulfuric acid
- Sources
- Sulfur dioxide
- sources
- volcanoes
- volcanoes
- uses
- used as bleach during
manufacture of paper from
wood pulp
- bleaching silk as well
- bleaching silk as well
- preserve food and drinks
- kills present bacteria
- sulfite ions usually added
- SO3 (2-) + 2H (+) -------> SO2 + H20
- SO3 (2-) + 2H (+) -------> SO2 + H20
- kills present bacteria
- used as bleach during
manufacture of paper from
wood pulp
- It is the gas given off when sulfur burns
- S + O2 -----> SO2
- S + O2 -----> SO2
- also made from roasting ores
- 2ZnS + 3O2 ----> 2ZnO + 2SO2
- 2ZnS + 3O2 ----> 2ZnO + 2SO2
- sources
- Sulfuric acid
- is a dibasic acid.
- It has 2 hydrogen ions per molecule that can react
- H2SO4 + 2NaOH ----> NaSO4 + H20
- sulfuric acid + sodium hydroxide -----> sodium sulfate + water
- sulfuric acid + sodium hydroxide -----> sodium sulfate + water
- H2SO4 + 2NaOH ----> NaSO4 + H20
- It has 2 hydrogen ions per molecule that can react
- H2SO4
- it is a strong acid with
typical acid properties
- reacts with metals above hydrogen in
reactivity series to form a salt and
hydrogen
- H2SO4 + Zn ----> ZnSO4 + H2
- H2SO4 + Zn ----> ZnSO4 + H2
- reacts with metal oxide to
form salt and water
- H2SO4 + MgO ---> MgSO4 + H20
- H2SO4 + MgO ---> MgSO4 + H20
- reacts with metal
hydrixide to form salt and
water
- H2SO4 + 2KOH ----> K2SO4 + 2H2O
- H2SO4 + 2KOH ----> K2SO4 + 2H2O
- reacts with metal carbonate to
form salt, water and carbon
dioxide
- H2SO4 + Na2CO3 ---> Na2SO4 + H20 + CO2
- H2SO4 + Na2CO3 ---> Na2SO4 + H20 + CO2
- can form hydrogensulfates
by replacement of one of
hydrogen ions
- H2SO4 + NaOH ---> NaHSO + H20
- H2SO4 + NaOH ---> NaHSO + H20
- reacts with metals above hydrogen in
reactivity series to form a salt and
hydrogen
- is a dibasic acid.
