    Calculating 'n' in Nernst Equation for Fe3+ and I- Reaction

    Is the answer wrong?? you use H+ and OH- when it is given that the reaction is carried out in acidic or basic medium.Nothing is given so we have to consider it being carried out in neutral medium.Apply the ion-electron balancing for neutral medium method.Waise there's no need of thinking about...

    Calculating 'n' in Nernst Equation for Fe3+ and I- Reaction

    i too did it using ion-electron method Step 1 balance the no of atoms -"so we put a 3 on left I-" Step 2 balance the charge - "there's an excess of charge(2 units) on right side so we add 2 e-there"

    Equilibrium Constant from Electrode Potentials

    \DeltaGo = -nFEo and \DeltaG = -nFE are two different equations.You are combining them.At equilibrium \DeltaG=0 doesn't mean that Eo=0 but it means E=0 i.e. electric potential at that time is equal to zero.Eo is constant quantity for any reaction and if it becomes zero the reaction can't...

    Calculating 'n' in Nernst Equation for Fe3+ and I- Reaction

    writing the half equations 2Fe+3 + 2e- --------> 2Fe+2 3I- --------> I3- + 2e- so there is total exchange of 2 electrons ,so n = 2

    Significance of wave function and its sign

    thanx for help... One more question In many books i have seen that while describing the \Psi vs radial distance 'r' graph of any orbital ,it is shown in two ways.For example 1s orbital - in one way they write it such that whole graph is in +ve phase [y = e^-x graph] whereas in other way the...

    Significance of wave function and its sign

    I have three question regarding the electronic wavefunction \Psi Ques 1 What does value of wavefunction of any orbital signify ? Is it just a mode of calculating other quantities like probability amplitude etc. or does it have a significance in itself ? Ques 2 What does the...
