Total number of species from the following which can undergo disproportionation reaction ___________. H 2 O 2 , ClO 3 - , P 4 , Cl 2 , Ag , Cu + 1 , F 2 , NO 2 , K +

Step-by-step solution

The compounds or ions or elements in which central atom has intermediate oxidation state undergo a disproportionation reaction. Disproportionation reactions are the reactions in which the same element/compound gets oxidised and reduced simultaneously. 1) Cu + → Cu 2 + + Cu 2) 2 H 2 O - 1 2 → H 2 O - 2 + O 0 2 3 ) 3 Cl 2 + 6 OH − → 5 Cl − + ClO 3 − + 3 H 2 O 4 ) 2 NO 2 ( g ) + 2 OH − ( aq ) → NO 2 − ( aq ) + H 2 O ( l ) + NO 3 − 5 ) P 4 + 3 OH - + 3 H 2 O → PH 3 + 3 H 2 PO 2 - Here, the chlorine reactant is in oxida
