The oxygen carrying pigment, oxy-hảemocyanin, containing two copper ions is diamagnetic, because

the two copper ions are in +1 oxidation state

one of the copper ions is in+1 oxidation state and the other is in +2 oxidation state

there are strong anti-ferromagnetic interactions between the two copper ions

there are ferromagnetic interactions between the two copper ions

Text Solution

Verified by Experts

Copper forms two oxides . For the same amount of copper, twice as much oxygen was used to form first oxide than to form second one. What is the ratio of the valencies of copper in first and second oxides ?

How much time would it take in minutes to deposit 1.18 g of metallic copper on a metal object when a current of 2.0 A is passed through the electrolytic cell containing Cu ^2 +ions? [ Molar mass of Cu =63.5 g /mol;IF=96,500 Cmol^-1]

The formation of the oxide ion O^(2-) (g) requires first an exothermic and then an endothermic step as shown below, O(g)+ e^(-) = O^(-)(g), DeltaH^(@)= -142kJmol^(-1) O^(-)(g) +e^(-) =O^(2-)(g), DeltaH^(@)= 844 kJmol^(-1) This is because : oxygen is more electronegative, oxygen has high electron affinity, O^(-) ion will tend to resist the addition of another electron , O^(-) ion has comparatively larger size than oxygen atom
