CoCl2 + KNO2 + CH3COOH ---> [X] + H2O + KCl + CH3COOK + NO
(Unbalanced equation)
Which of the following statement is correct ?
(A) X is a yellow crystalline solid insoluble in water.
(B) X is a green coloured compounds and water soluble.
(C) IUPAC name of X is potassium hexanitrito –N– cobaltate (II)
(D) The compound X is an inner orbital complex.
1hmmmmmm.....
X is K3 [Co ( NO2 )6] i.e. potassium hexanitrito –N– cobaltate (III).
and its more precisely an orange coloured solid ( i think perhaps its dilute solution cn be comparable to yellow) and its an inner orbital complex.
so, ans. are A and D. precisely , only D.
