Question: Write the net ionic equations for the following reactions between aqueous solutions: (a) Sodium acetate and nitric acid (b) Hydrobromic acid and strontium hydroxide (c) Hypochlorous acid and sodium cyanide (d) Sodium hydroxide and nitrous acid Answer: (a) \(\mathrm{H}^{+} \mathrm{(aq)} + \mathrm{C}_{2} \mathrm{H}_{3} \mathrm{O}_{2}^{-} \mathrm{(aq)} \rightarrow \mathrm{HC}_{2} \mathrm{H}_{3} \mathrm{O}_{2} \mathrm{(aq)}\) (b) \(2 \mathrm{H}^{+} \mathrm{(aq)} + 2 \mathrm{OH}^{-} \mathrm{(aq)} \rightarrow 2 \mathrm{H}_{2}\mathrm{O} \mathrm{(l)}\) (c) \(\mathrm{HOCl} \mathrm{(aq)} + \mathrm{CN}^{-} \mathrm{(aq)} \rightarrow \mathrm{HCN} \mathrm{(aq)} + \mathrm{OCl}^{-} \mathrm{(aq)}\) (d) \(\mathrm{OH}^{-} \mathrm{(aq)} + \mathrm{HNO}_{2} \mathrm{(aq)} \rightarrow \mathrm{NO}_{2}^{-} \mathrm{(aq)} + \mathrm{H}_{2}\mathrm{O} \mathrm{(l)}\)
