Students can develop alternative conceptions (commonly called misconceptions) in relation to some core concepts in chemistry. Consider each of the following ideas expressed by students and suggest how you would address these incorrect ideas through experimental work and class discussion: (i) Sugar (e.g. glucose) and salt (e.g. NaCl) both dissolve in water and therefore both are ionic compounds. (ii) Breaking bonds releases energy. (iii) Adding reactant A to reactant B will always produce the same products as adding reactant B to reactant A.

Students can develop alternative conceptions (commonly called misconceptions) in
relation to some core concepts in chemistry. Consider each of the following ideas
expressed by students and suggest how you would address these incorrect ideas
through experimental work and class discussion:
(i) Sugar (e.g. glucose) and salt (e.g. NaCl) both dissolve in water and therefore
both are ionic compounds.
(ii) Breaking bonds releases energy.
(iii) Adding reactant A to reactant B will always produce the same products as
adding reactant B to reactant A.
(iv) In the reaction of Fe + S --> FeS, adding 10 g of Fe to 10 g S will produce 10g of FeS.
