Understanding● Most acids have observable characteristic chemical reactions with reactive metals, metal oxides, metal hydroxides, hydrogen carbonates, and carbonates.
Guidance Bases which are not hydroxides, such as ammonia, soluble carbonates, and hydrogen carbonates should be covered. ● Salt and water are produced in exothermic neutralization reactions. |
Application 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 The colour changes of different indicators are given in the data booklet in section 22. |
