The reactants are completely reacted

It has been transformed into a product

The most typical is the combination reaction

Simply put it is to merge similar items

On the double decomposition reaction

Exchange between substances

At the end of the reaction

There is almost nothing but exchanging elements

As for the redox reaction

Losing electrons is oxidation

And obtaining electrons is reduction

The oxidant and reductant are the opposite

What has not changed in the reaction is the bystander ion

It doesn't react no matter how the reactant changes

It's like doing it many times but there is no result

Some reaction equations can ignore it

Mention about acid-base reaction

It is hydrogen ion and hydroxide ion

These two react with each other

The final product is water molecules

In which the reactants can be ionized

Always carrying those two ions

Concentration of product in aqueous solution

Depends on whose concentration is high

What has not changed in the reaction is the bystander ion

It doesn't react no matter how the reactant changes

It's like doing it many times but there is no result

Some reaction equations can ignore it

As for the displacement reaction

Simple substances are converted into compounds

On the basis of the original

It adds another element
