(d) \(\mathrm{NH}_{4} \mathrm{Cl}(a q)+\mathrm{NaOH}(a q) \rightarrow \mathrm{H}_{2} \mathrm{O}(l)+\mathrm{NH}_{3}(g)+\mathrm{NaCl}(a q)\)

ANSWER:

Step 1 of 4

Here, we have to write the balanced complete ionic and net ionic equations for each reaction.

In a balanced chemical equation, the number of each type of atom or ion on both sides of the equation should be equal.

(a) \(\mathrm{HI}(a q)+\mathrm{KOH}(a q) \rightarrow \mathrm{H}_{2} \mathrm{O}(l)+\mathrm{KI}(\mathrm{aq})\)

Total ionic reaction is:

\(\mathrm{H}^{+}(\mathrm{aq})+\mathrm{I}^{-}(\mathrm{aq})+\mathrm{K}^{+}(\mathrm{aq})+\mathrm{OH}^{-}(\mathrm{aq}) \rightarrow \mathrm{H}_{2} \mathrm{O}(\mathrm{l})+\mathrm{K}^{+}(\mathrm{aq})+\mathrm{I}^{-}(\mathrm{aq})\)

Spectators: \(\mathbf{I}^{-}(\mathrm{aq}), \mathrm{K}^{+}(\mathrm{aq})\)

Net Ionic Equation is : \(\mathrm{H}^{+}(\mathrm{aq})+\mathrm{OH}^{-}(\mathrm{aq}) \rightarrow \mathrm{H}_{2} \mathrm{O}(\mathrm{l})\)
