SINGLE REPLACEMENT
REACTION CATEGORY
In these reactions, a free element reacts with a compound
to form another compound and release one of the elements
REACTION DESCRIPTION of the original compound in the elemental state.There are
two different possibilities:
1. One cation (+ ion) replacesanother.
2. One anion (- ion) replaces another.
I.AB + C

*Metals from Li to Na will replaceH
from acids and water; from Mg to Pb
they will replaceH from acidsonly.
2. A nonmetalcan also replaceanothernonmetalfrom a compound.This replacementis usuallylimited to the halogens(F2
as y(
Cl2,Br2, and 12). The activity of the halogensdecreases
go down the Group (17) of the periodictable.
