Na3PO4+KOH-->NaOH + K3PO4

Let us study about this reaction

Explanation:

This given reaction is a chemical reaction that is : Double decomposition reaction.

In this reaction, there is a reaction between two compounds in which they mutually interchange their ions.

That is:

AB + CD - --> AC + BD

Similarly in this we have:

Na3PO4+KOH-->NaOH + K3PO4

The double decomposition reaction is either:

Precipitation reaction : resulst in the formation of ppt.

Neutralization reaction : results in the formation of neutral substance
