Self Assessment Checklist – Acids, Bases and Salts

Knowing the learning objectives is the first step in acing Chemistry. Master the essential concepts and apply them to interesting Chemistry questions confidently. Topical syllabus objective checklists are available here for your self-assessment. These checklists are based on Cambridge O-level Syllabus. Conduct self assessment when you revise. Tick against objectives that you can confidently say ‘I Can Do It’. Revise objectives that you are unsure of. Knowing what you need to know builds confidence in tackling questions. 

Work hard. Work smart. All the best.

Self Assessment Checklist - Acids and Bases

  I can do this!
aDefine acids as substances that produce hydrogen ions in aqueous solution and describe their effects on Universal Indicator.
bDescribe how to test hydrogen ion concentration and hence relative acidity using Universal Indicator and the pH scale.
cDescribe qualitatively the difference between strong and weak acids in terms of the extent of ionisation.
dDescribe the characteristic properties of acids as in reactions with metals, bases and carbonates.
eState the uses of sulfuric acid in the manufacture of detergents and fertilisers; and as a battery acid.
fDefine alkalis as substances that produce hydroxide ions in aqueous solution and describe their effects on Universal Indicator.
gDescribe the reaction between hydrogen ions and hydroxide ions to produce water as neutralisation.
hDescribe the importance of controlling the pH in soils and how excess acidity can be treated using calcium hydroxide.
iDescribe the characteristic properties of bases in reactions with acids and with ammonium salts.
jClassify oxides as acidic, basic, amphoteric or neutral based on metallic/non-metallic character.

Self Assessment Checklist - Salts

  I can do this!
aDescribe the general rules of solubility for common salts to include nitrates, chlorides (including silver and lead), sulfates (including barium, calcium and lead), carbonates, hydroxides, Group I cations and ammonium salts
bSuggest a method of preparing a given salt from suitable starting materials, given appropriate information.
cDescribe the techniques used in the preparation, separation and purification of salts. The methods for preparation include precipitation and titration together with reactions of acids with metals, insoluble bases and insoluble carbonates.
