OBJECTIVES
Expected observation
• Blue Litmus paper will turn purple in the solution containing the acid as more ammonia is being
added.
Conclusion
• Since reaction of Ammonia and Sulphuric acid is an acid base reaction a salt and water is formed by
evaporating leaves the salt behind.
ASSESSMENT EXERCISE 13.2 SULPHUR COMPOUNDS
1. During the production of sulphuric acid the reaction in the converter is given by the
equation:
2𝑆𝑂2 (𝑔)+𝑂2 𝑔 ⇋ 2𝑆𝑂3 (𝑔)∆H= -197 KJ/mol
Explain the effect of the following changes on the rate of reaction and yield at equilibrium.
a. Increased applied pressure at constant temperature. [3]
b. Increased temperature at constant volume. [3]
c. The addition of excess O2 at constant temperature and volume. [2]
d. Sulphur dioxide gas is passed over a catalyst. What is the catalyst and what is its purpose? [3]
e. Name two industrial products which are made using sulphuric acid? [2]
