Question

Consider the separation of inorganic and organic anions in Figure.

(a) What is the probable charge $\mathbf{\left(}{\mathbf{X}}^{\mathbf{n}\mathbf{-}}\mathbf{\right)}$of pyruvate (peak 10), 2-oxovalerate(peak 16), and maleate (peak 28)? (Hint: Look at the ions around the peaks in question.)

(b) Iodide (peak 44) is a-1ion. Explain its strong retention.

Short answer

Polarizability:It is tendency of a compound to acquire an electric dipole moment in proportion to electric field which is applied, when a compound is exposed to an electric field.

Step-by-step solution

Solution of subpart (a) determination of charges

The probable charge $\left({\mathrm{X}}^{\mathrm{n}-}\right)$of pyruvate (peak 10), 2-oxovalerate (peak 16), and maleate (peak 28) by looking at the ions around the peaks are as follows:

Pyruvate -1

2-oxovalerate -1

Maleate -2

Solution of subpart (b) retention of Iodide (peak )

The iodide ion is highly polarizable.
