Syllabus Objectives – Acids and Bases

Self Assessment Checklist

Acids and Bases I can do this!
(a) Define acids as substances that produce hydrogen ions in aqueous solution and describe their effects on Universal Indicator.  
(b) Describe how to test hydrogen ion concentration and hence relative acidity using Universal Indicator and the pH scale.  
(c) Describe qualitatively the difference between strong and weak acids in terms of the extent of ionisation.  
(d) Describe the characteristic properties of acids as in reactions with metals, bases and carbonates.
(e) State the uses of sulfuric acid in the manufacture of detergents and fertilisers; and as a battery acid.
(f) Define alkalis as substances that produce hydroxide ions in aqueous solution and describe their effects on Universal Indicator.
(g) Describe the reaction between hydrogen ions and hydroxide ions to produce water,

H+ + OH → H2O, as neutralisation.

(h) Describe the importance of controlling the pH in soils and how excess acidity can be treated using calcium hydroxide.
(i) Describe the characteristic properties of bases in reactions with acids and with ammonium salts.  
(j) Classify oxides as acidic, basic, amphoteric or neutral based on metallic/non-metallic character.
