We can use the term _________ to describe the ability of a metal cation to displace other metal cations from polyatomic anions
|
reactivity
|
|
|
A _______ reaction is when one metal cation displaces another that is associated with a polyatomic anion
|
single replacement
|
|
|
What is the evidence that a single replacement reaction has occured?
|
The formation of metal precipitate and may include color change
|
|
|
How can you tell if there will be a reaction for the single replacement reactions?
|
A metal that is higher on the reactivity scale can displace a metal that is lower on the reactivity scale
|
|
|
A _______ reaction is when the cations and anions of the reactants trade partners to form products
|
double replacement
|
|
|
What 2 cations commonly form precipitates?
|
silver and sodium cations
|
|
|

|
cations are similar in reactivity; anions are similar in reactivity; anions are identical
