Understand the Problem
The image contains notes on chemical tests for identifying cations and anions, specifically focusing on group elements and confirmation tests for aluminium. It outlines experimental procedures and observations related to the presence of lead, copper, and aluminium cations in various salt solutions.
Answer
Aluminium Nitrate (Al(NO₃)₃).
The given salt is Aluminium Nitrate (Al(NO₃)₃).
Answer for screen readers
The given salt is Aluminium Nitrate (Al(NO₃)₃).
More Information
This test uses precipitation reactions to identify metal ions. The presence of aluminum is confirmed by the solubility of the precipitate in excess NaOH.
Tips
Ensure to observe the solubility of precipitates in excess reagents for confirmation.
