Clarification details
Outcome 1
ER 1.1
The accuracy required for the titration data is not stated and should be taken as the accuracy expected for the level 2 acid-base titration, 8940.
ER 1.2
The balanced equation is provided for one-step reactions. However, the student must determine the overall stoichiometry for a two-step process using the one-step equations provided.
Outcome 2
ER 2.1
In writing half-equations and overall equations, it is expected that examples are not those which would be appropriate to level 2.
