Question

Write the cations and anions present, if any, in the following :
(a) CH₃COONa
(b) NaCl
(c) H₂
(d) NH₄NO₃

Answer 1

(a)$\begin{array}{ccccc}{\mathrm{CH}}_3\mathrm{COONa}:& \mathrm{Cation}:& {\mathrm{Na}}^{+}& \mathrm{Anion}:& {\mathrm{CH}}_3{\mathrm{COO}}^{-}\end{array}$
(b) $\begin{array}{ccccc}\mathrm{NaCl}:& \mathrm{Cation}:& {\mathrm{Na}}^{+}& \mathrm{Anion}:& {\mathrm{Cl}}^{-}\end{array}$
(c) H₂ is a neutral molecule; therefore, it will not have a cation or an anion.
(d)$\begin{array}{ccccc}{\mathrm{NH}}_4{\mathrm{NO}}_3:& \mathrm{Cation}:& {\mathrm{NH}}_4^{+}& \mathrm{Anion}:& {\mathrm{NO}}_3^{-}\end{array}$
