A compound contains atoms of three elements A,B And C. If the oxidation number of A is +2, B Is +5 and that Of C Is −2, the possible formula of the compound is
Step 1: Given
The oxidation numbers of the elements, A, B, C are respectively.
Step 2: Deriving possible formulae of compound
The formula of a compound with elements A, B, and C will be of the form
where x,y, and z are the atomicities of individual atoms respectively.
Step 3: Formula used
A compound is always neutral, so the oxidation number of the compound is zero.
Hence, the net oxidation number of the individual atoms is zero.
Hence calculating in a similar way,
Step 4: Applying the hit and trial method for the deriving formula for the compound
Restricting it to conditions that the maximum oxidation state could be , by the Hit and Trial method, the possible solutions of (x,y,z) could be
Both the sets are possible as the elements are unknown.
Hence the compounds are
