Answer: Option (A) is the correct answer.
Explanation:
Atomic number of sodium is 11 and its electronic configuration is
.
In order to gain stability, sodium loses one electron and hence it forms a positive ion
.
Thus, we can conclude that when sodium combines with chlorine, it has a net charge of +1 because sodium loses a negative electron when forming chemical bonds.
An electrolyte is a substance that releases ions when it is dissolved in water. Electrolytes are divided into salts, ions and bases. In this case, the electrolyte is H₃PO₄ as it releases H+ ions and PO₄⁻³ ions when it is dissolved in water.
