Question

Which of the following salt gives white precipitate with A g N O subscript 3 end subscript solution and dil. H subscript 2 end subscript S O subscript 4 end subscript solution and gives green flame test

  1. C u C l subscript 2 end subscript    
  2. B a C l subscript 2 end subscript    
  3. P b C l subscript 2 end subscript    
  4. C u left parenthesis N O subscript 3 end subscript right parenthesis subscript 2 end subscript    

The correct answer is: B a C l subscript 2 end subscript


    Flame colour of Ba salt is green
    2 A g N O subscript 3 end subscript plus B a C l subscript 2 end subscript stack rightwards arrow 2 A g C l plus with text White ppt. end text below B a left parenthesis N O subscript 3 end subscript right parenthesis subscript 2 end subscript.
