Question

Which of the following solution cannot act as buffer?

  1. N a H subscript 2 end subscript P O subscript 4 end subscript plus H subscript 3 end subscript P O subscript 4 end subscript    
  2. C H subscript 3 end subscript C O O H plus C H subscript 3 end subscript C O O N a    
  3. H C l plus N H subscript 4 end subscript C l    
  4. H subscript 3 end subscript P O subscript 4 end subscript plus N a subscript 2 end subscript H P O subscript 4 end subscript    

The correct answer is: H C l plus N H subscript 4 end subscript C l
