In a precipitation reaction, a subclass of exchange reactions, an insoluble material (a precipitate) forms when solutions of two substances are mixed. To predict the product of a precipitation reaction, all species initially present in the solutions are identified, as are any combinations likely to produce an insoluble salt.

If a solid is formed (a precipitate) If water is formed If a gas is formed If electrons are transferred Then it is likely that a chemical reaction took place. Also, if a new odor is produced, a new color is produced, or a change in energy (temperature, light, sound) occurs it is likely that a reaction occurred.

Sep 30, 2012 · §4.6 Precipitation ReactionsHow to predict a precipitation reaction:1) Swap the anions and cations.2) Consult the solubility rules. If any of the “products” are insoluble in water, a precipitation reaction has occurred. Otherwise, there is no reaction.
A double-replacement reaction exchanges the cations (or the anions) of two ionic compounds. A precipitation reaction is a double-replacement reaction in which one product is a solid precipitate. Solubility rules are used to predict whether some double-replacement reactions will occur.
The overall reaction is simply the combination of the two half reactions and is shown by adding them together. Because we have two electrons on each side of the equation, they can be canceled. This is the key criterion for a balanced redox reaction: the electrons have to cancel exactly.
This is a precipitation reaction, where two soluble salts are mixed together in solution forms to make a precipitate. So, we can now write the ionic equation for this reaction, that is: #Fe^(2+)(aq)+2Cl^(-)(aq)+2Na^+(aq)+2OH^(-)(aq)->2Na^+(aq)+2Cl^(-)(aq)+Fe(OH)_2(s)downarrow#
8) What causes a precipitation reaction to occur between two soluble compounds? Answer: A precipitate, or insoluble compound, forms from a pair of the ions present. This "traps" some of the ions into a newly formed compound causing a reaction. Diff: 1 Type: SA Var: 1 Page Ref: 4.4
