Assertion : A simplified coordination number ratio for ions of any ionic crystal is inverse of molar ratio. Reason : Coordination number ratio of cation to anion in CaF_(2) (fluorite structure) is 8 : 4.
Assertion : The covalence of nitrogen in N_2O_5 is 5. Reason : Nitrogen can expand its covalence beyond 4.
Assertion : Absence of blood red colouration, during the Lassaigne's test for nitrogen definitely shows the absence of sulphur in the organic compound. Reason : Organic compounds containing both nitrogen and sulphur will necessarily give blood red colouration during the Lassaigne's test for nitrogen.
Assertion : The complex K_3 [Cr(C_2O_4)_3] when present in aqueous solution, will give test for K^(+), Cr^(3+) and oxalate ions. Reason : The complex K_3[Cr(C_2O_4)_3] will dissociate completely in solution.
