L3 - Reactivity of Metals and Acids

objectives

Understandings:

• Most acids have observable characteristic chemical reactions with reactive metals, metal oxides, metal hydroxides, hydrogen carbonates and carbonates.

• Salt and water are produced in exothermic neutralization reactions.

Applications and skills:

• Balancing chemical equations for the reaction of acids.

• Identification of the acid and base needed to make different salts.

• Candidates should have experience of acid-base titrations with different indicators.

Guidance:

• Bases which are not hydroxides, such as ammonia, soluble carbonates and hydrogen carbonates should be covered.

• The colour changes of different indicators are given in the data booklet in section 22.
