Question

Fill in the blank with appropriate words.
The electrolytic solution is always neutral because the total charge on $\underset{–}{\left(i\right)}$ is equal to $\underset{–}{\left(ii\right)}$ on $\underset{–}{\left(iii\right)}$. Unlike the metallic conductor, the electrolyte conducts the electric current by virtue of movement of its $\underset{–}{\left(iv\right)}$. The property due to which a metal tends to go into solution in term of positive ions is known as $\underset{–}{\left(v\right)}$.
(i), (ii), (iii), (iv) and (v) respectively are:

• A. cations, partial charge, anions, electrons, reduction
• B. cations, total charge, anions, ions, oxidation
• C. cations, ionic charge, anions, atoms, dissolution
• D. cations, partial charge, anions, molecules, electrolysis

Answer 1

Answer: (B)

cations, total charge, anions, ions, oxidation

To maintain neutrality, the total charge on cation is equal to the total charge on anion.

Metallic conductor contains ions. Hence, the current is due to the movement of ions.

Oxidation is the loss of an electron.

Hence, metals undergo oxidation.
