Because weak electrolytes do not completely dissociate into ions, whenever two ions can get together to form a  weak electrolyte there will be a net ionic equation. For example, HCl (aq)  + NaC 2 H 3 O 2 (aq)    HC 2 H 3 O 2 (aq)  + NaCl (aq) Writing out the complete ionic equation we obtain: H + (aq)  + Cl - (aq)  + Na + (aq)  + C 2 H 3 O 2 - (aq)    HC 2 H 3 O 2 (aq)  + Na + (aq)  + Cl - (aq) Removing the spectator ions we obtain the net ionic equation: H + (aq)  + C 2 H 3 O 2 - (aq)    HC 2 H 3 O 2 (aq) Water is also considered to be a weak electrolyte. That is, only a small fraction of the

Unformatted text preview: H 2 O molecules in water dissociate to form H + and OH-ions. Therefore, any reaction that leads to the formation of water will have a net ionic equation. Let's look at a classic example of an acid reacting with a base. HCl (aq) + NaOH (aq) → NaCl (aq) + H 2 O (l) Removing the spectator ions we obtain the net ionic equation: H + (aq) + OH-(aq) → H 2 O (l)...
