NEET Chemistry Functional Group Tests MCQ Question
In the qualitative analysis of Group-V cations, when barium carbonate is dissolved in acetic acid and treated with potassium chromate, what is the stoichiometric ratio of acetic acid to barium chromate formed?
2:1
1:1
1:2
3:2
Correct Answer
Detailed Explanation
From the NCERT context, when barium carbonate reacts with acetic acid, it forms barium acetate. This barium acetate then reacts with potassium chromate to form barium chromate. The balanced equations indicate a 2:1 ratio of acetic acid to barium chromate.
