|
Combination Reaction |
When two reactants combine to give one product. A + B ---> AB |
|
|
Decomposition |
When some substances are heated, they can be broken down or decomposed. AB ---> A + B |
|
|
Displacement/Substitution |
A metal or non-metal may displace another from its salt. A + BX ---> AX + B |
|
|
Double decomposition |
- This means that two things are being broken up. - When salt solutions are being mixed together, they exchange ions. - The reaction starts off with two solutions and in exchange you always end up with a solid and a solution. AB(aq) + CD(aq) ---> AD(s) + CB(aq) |
|
|
Neutralisation |
- Involves the reaction between the acid and the base. - A base is a metallic oxide or hydroxide. - Acids and bases react until their pH is exactly 7 or neutral. - Hence, water is always produced. |
|
|
Reversable |
Reactions proceeds from reactants to products or from products or from products to reactants.
A + B ↔ AB |
|
|
Redox |
Involves (i) reduction (gain of electrons) (ii) oxidation (loss of electrons) |
