Understanding reaction types

Recommended Posts

"The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion."

Where do (a) precipitation (b) acid-base and (c) redox reactions fit under those 5 categories.

Thanks

Tell us what you think about it first and then maybe we can guide you a bit.

Is this really a homework question or just a request for understanding of material you have been presented with in a course or read ?
I ask because it looks much more like the latter and such questions can legitimately be asked in the main Chemistry sections.

 

OK so there are several different classification schemes for chemical reactions.
Each has its own point of view and the schemes are not mutually exclusive.

So you first list is about reactants and products.
That is what substances you start with and what substances you end up with.

Say

A + B = C   -  combination

A = B + C   -  decomposition or dissociation

AB + CD = AD + CB  - replacement or elimination

and so on.

There are further reactions types than your first list in this viewpoint.

 

Your second list narrows down these wider categories in some way.

So

Acid + Base = Salt + Water 

Is an elimination reaction where CB is always water and AD is always the salt.
(This has been extended beyond water in more advanced Chemistry)

If the reaction is in solution and AD is precipitated then this is also a precipitation reaction.
So you can see some overlap in the categories beginning to appear.

Oxidation is the addition of oxygen or the removal of hydrogen
Reduction is the removal of oxygen or the addition of hydrogen

Since combustion is one of these (which one  ?)
It is a redox reaction.

 

Note that all these classification types start with substances and end with different substances.


In more advanced Chemistry your will meet others views which are about what goes on during the reaction and the movement of electrons and/or protons from one substance to another.
These may be called reaction mechnaism views.

 

Where are you in your studies to have been given the first list as the basic 5 ?
