What type of aqueous chemical reactions are there?
|
Precipitation reactions;
Acid-base neutralization reactions and; Oxidation-Reduction reactions. |
|
Describe a Precipitation reaction.
|
Here soluble reactants yield an insoluble solid product, most of these reactions take place where the anions and cations of two ionic compounds change partners.
AB(aq) + CD(aq) -> BC(aq) + AD(s) |
|
Describe a Acid-base neutralization reaction.
|
Here an acid reacts with a base to yield water and an ionic compound called salt, water is produced by the removal of H and OH ions from the solution.
HCl(aq) + NaOH(aq) ->H2O(l) + NaCk(aq) |
|
Describe a oxidation-reduction reaction.
|
-This is also called Redox reaction.
-Here one or more electrons are transfered between reaction partners. |
|
What does Oxidation mean?
|
It means that an atom looses electrons.
|
|
What does reduction mean?
|
It means that an atom gains electrons.
|
|
Name other normal chemical reactions.
|
Combination reaction;
Decomposition reaction; Displacement reaction, and; Partner exchange reaction. |
|
Describe combination reaction.
|
This happens when the reactants are fewer than products, this type of reaction needs a burner heat to be performed.
A+B -> C |
|
Describe decomposition reaction.
|
This happens when the products are fewer than the reactants, this reaction need to be made in heat to be performed.
C -> A + B |
|
Describe displacement reaction.
|
Here the atoms or ions at one substance take the place of atoms or ions in a compound.
A + BC -> AC + B - Metals normally displace hydrogen from acids, they need to be more active than hydrogen. Fe + H2SO4 eg. |
|
Describe Partner exchange reactions.
|
Two or more products change partners.
AB + CD -> AC + BD |
