A neutralization reaction is a type of double replacement reaction. A neutralization reaction occurs when an acid reacts with an equal amount of a base. This reaction usually produces a salt. One example, hydrochloric acid reacts with disodium iron tetracarbonyl to produce the iron dihydride: 2 HCl + Na 2 Fe(CO) 4 → 2 NaCl + H 2 Fe(CO) 4
Another example of a double displacement reaction is the reaction of lead(II) nitrate with potassium iodide to form lead(II) iodide and potassium nitrate: + + Forward and backward reactions According to Le Chatelier's Principle , reactions may proceed in the forward or reverse direction until they end or reach equilibrium .
Although this is a reaction solely of the dissociated ions in solution, it is sometimes referred to as a double displacement reaction: [1] Pb(NO 3) 2 + 2 KI → 2 KNO 3 + PbI 2. At higher temperature, this substance easily re-dissolves by dissociation to its colorless ions. The actual change (net ionic equation) is thus:

Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
Alternatively the reaction can be carried out with lead cyanate and ammonia. [4] The actual reaction taking place is a double displacement reaction to form ammonium cyanate: Pb(OCN) 2 + 2 NH 3 + 2 H 2 O → Pb(OH) 2 + 2NH 4 (OCN) Ammonium cyanate decomposes to ammonia and cyanic acid which in turn react to produce urea: NH 4 (OCN) → NH 3 ...
Metathesis reactions are another term for double-displacement; that is, when a cation displaces to form an ionic bond with the other anion. The cation bonded with the latter anion will dissociate and bond with the other anion. [1] A common metathesis reaction in aqueous solutions is a precipitation reaction.
