for oxidation or reduction to occur, electrons have to be involved. Either they are lost or gained, and as you probably know, loosing electrons is defined as oxidation and gaining electrons as reduction. In the two examples you give, the substances have already lost or gained electrons and exist as charged particles in solution; they just switch partners. For example, in the classic definition of neutralization, a base contains ( OH- ) ions and an acid contains ( H+ ) ions. If they combine there are no electrons transferred so no oxidation or reduction takes place, and the remaining ions also combine with no electron shifts. Precipitation reactions are exactly the same except that when certain ions in solution combine,( with no electrons exchanged), the substance formed is insoluble and precipitates.

How can one identify a redox reaction?
A redox reaction can be identified by the transfer of electrons between reactants. Look for changes in oxidation states of elements involved in the reaction to determine if it is a redox reaction.
What is another name for oxidation-reduction reaction?
another name for an exchange reaction but metathesis reaction. This reaction usually occurs in hydrolysis and is AB+CD=AD+CB
How can one determine if a chemical reaction is a redox reaction?
One can determine if a chemical reaction is a redox reaction by identifying if there is a transfer of electrons between the reactants. In a redox reaction, one substance loses electrons (oxidation) while another gains electrons (reduction). This transfer of electrons indicates a redox reaction is taking place.
How can you determine if a chemical reaction is a redox reaction?
A redox reaction can be determined by looking for changes in the oxidation states of the elements involved. If there is a transfer of electrons from one substance to another, it is likely a redox reaction. Additionally, the presence of a change in color, formation of a gas, or release of heat can also indicate a redox reaction.
How do you determine if a chemical reaction is a redox reaction?
A redox reaction can be determined by looking at whether there is a transfer of electrons between the reactants. If one substance loses electrons (oxidation) and another gains electrons (reduction), then it is a redox reaction.
