Single Displacement Flashcards
Single Displacement Definition
In this type of reaction, one element displaces another element in a compound, producing a new compound and a new element
A + BC = B + AC
Single displacement with metal and ionic compound or acid
In single displacement reactions involving a metal and an ionic compound or acid, it is always the positive ion (cation) that is displaced in the compound
How to know if it will displace?
To determine whether or not a reaction between an element and a compound will proceed, look at the relative positions of the two metals in the activity series
If the higher (more active) metal is the element, the reaction proceeds
If the higher metal is in the compound, no reaction occurs.
The Halogen activity series
The elements of the halogen family also have their own activity series based on displacement reactions
The trend in halogen reactivity is the same as the trend in electronegativity of these elements!
Single Displacement Options
metal + aqueous ionic compound
Metal must be above metal ion on activity series
Single Displacement Options
metal + acid
Metal must be above hydrogen on activity series
Single Displacement options
metal + water [treat was as H+(OH-) and displace H+]
Metal must be one of first five on activity series
Single Displacement options
halogen + aqueous ionic compound containing halide
Halogen must be above haliade on activity series.
Halides are binary compounds made up of any other element and a halogen.
