In
each of the three reactions we have just considered,
the hydrogen atoms in the acid molecules
are ‘replaced’ by a ‘metal’
atom. The new substance has a giant structure
(due to a change in type of bonding).
 |
Hydrochloric
acid gives a ‘metal’ chloride. |
|
Sulfuric
acid gives a ‘metal’ sulfate.
|
|
Nitric
acid gives a ‘metal’ nitrate.
|
|
|
At the same time, the hydrogen atoms
do one of
the following:
|
form the elementary
substance hydrogen (H2) if the reaction
is with an elementary ‘metal’
|
|
go towards
making water if the reaction
is with a ‘metal’ oxide |
|
take part
in a rearrangement to give water and carbon
dioxide if the reaction is with a ‘metal’
carbonate. |
