Question 3

A technician tests a solution that may contain a halide ion and carbonate ions. Silver nitrate solution is added directly, without first adding an acid. A cream precipitate forms.

Evaluate whether this result is sufficient to identify the halide ion. Include the ionic equation, with state symbols, for the formation of the cream precipitate.
