    A stable complex is formed if EAN is equal to the atomic no. Of next noble gas. In [Fe(CN)6]4- EAN of Fe = 26-2+6*2=36 In [Fe(CN)6.]3- EAN of Fe=26-3+6*2=35 hence,[Fe(CN)6]4- is more stable.

    In chemistry, a racemic mixture, or racemate is one that has equal amounts of left- and right-handed enantiomers of a chiral molecule. The first known racemic mixture was racemic acid, which Louis Pasteur found to be a mixture of the two enantiomeric isomers of tartaric acid.

    The conductivity of a solution is directly proportional to the no. of ions in the solution. ie. When no. of ions is more the conductivity is high and vice versa. After dilution, when we consider a unit volume of solution, the no. of ions in the unit volume is less. Therefore conductivity decreases.
