A comparative study of `E^(@)(M^(3+)|M^(2+))` values show varying trends. Choose the correct trends (along with possibe reason) among the following.
Among the first transition series (3d series) only copper has positive E^(Theta)M^(2+)//M value. Why?
Explain the variation in E_(m^(2+))^(0) //M 3d series .
`E_(M^(3+)//(M))^(@) = -0.036V` , `E_(M^(2+)//M)^(@)= -0.439V`. The value of standard electrode potential for the change, `M^(3+)(aq) + e^(-)rightarrow M^(2+) (aq)` will be :
A: Cu^(2+) is the only jon (M^2+) which has positive E_(red)^(@) (M^(2+)//M)) in 3d series. R: Cu has lower hydration enthalpy ascomparision to its I.E. and triangleH_(atm)
Explain the variation in E_M^(3+) //m^(2+)^(0) 3D Series.
(a) (i) Which types of ores can be concentrated by froth floatation method? Give two examples for such ores. (ii) Explain the variation in `E_(M^(3+)//M^(2+))^(@)` 3d series.
Explain the variation in E_(M^(2+)//M^(3+)+ 3d series
The only element with positive E^(@)(M^(2+)|M) potential in 3d series is…..
In 3d-series which element has positive E_(M^(2+)//M)^(@) value? Why?
Give reasons: Zn has highest value for `E^@(M^3+/M^2+) among 3d series elements.
The electrode potential of M^(2+)//M of 3d-series elements shows positive value of:
Which transition metal of 3d series has positive `E^@ (M^(2+)//M)` value and why ?
A: `Cu^(2+)` is the only ion `(M^2+)` which has positive `E_(red)^(@) (M^(2+)//M))` in 3d series. R: Cu has lower hydration enthalpy as comparision to its I.E. and `triangleH_(atm)`
E_(M^(2+//M))^(@) values are not regular for first row of transition metals (3d-series )
