Answer:

The correct answer is 17 meq/g

Explanation:

Ion exchange capacity (IEC) express the total of active sites of a resin in which ions are attached because the greater molecular weight.

The exchange Reaction can be represented as

R-H $R-H^{+} + Na^{+} + Cl^{-} -> R-Na^{+} + HCl_{aq}$

The IEC value (in meq/g) is determinated by using the next equation:

IEC=[(mL of NaOH)*(M of NaOH)]/mass of resin

IEC [(17 mL)*(0.5 M)/0.5]= 17 meq/g

When the element is reduced it gains electrons, maybe it's charge becomes more negative.
