Aluminum carbonate solution can be used to identify all the following cations except:
Understand the Problem
The question is asking which cation cannot be identified using aluminum carbonate solution among the given options, which includes Ca²⁺, Mg²⁺, Na⁺, and Ag²⁺.
Answer
Na+
The final answer is Na+.
Answer for screen readers
The final answer is Na+.
More Information
Aluminum carbonate is insoluble, so it can precipitate out certain cations. Sodium carbonate is soluble, so Na+ would not be identified with this test.
Tips
A common mistake is not correctly applying solubility rules for carbonates, which are mostly insoluble except for those of Group 1 metals.
