Question

Write the cations and anions present (if any) in the following compounds

1. ${\mathrm{CH}}_3\mathrm{COONa}$ (b) $\mathrm{NaCl}$ (c) ${\mathrm{H}}_2$ (d) ${\mathrm{NH}}_4{\mathrm{NO}}_3$ .

Answer 1

• The ion with negative charge are called anions.
• The ion with positive charge are called cations.

Explanation of part a-

The cations and anions present in ${\mathrm{CH}}_3\mathrm{COONa}$= ${\mathrm{CH}}_3{\mathrm{OO}}^{-}$is anion and ${\mathrm{Na}}^{+}$is cation.

Explanation of part b-

The cations and anions present in $\mathrm{NaCl}$=${\mathrm{Na}}^{+}$is cation and ${\mathrm{Cl}}^{-}$is anion

Explanation of part c-

It is molecular compound (no ions)

Explanation of part d-

The cations and anions present in ${\mathrm{NH}}_4{\mathrm{NO}}_3$=$\mathrm{NH}{4}^{+}$is cation and ${{\mathrm{NO}}_{3^{}}}^{-}$
