ЗKOH + H3PO4=K3PO4 + 3H2O <br> what is the reaction
pentagon [3]

Answer: The given reaction is a neutralization reaction.

Explanation:

When an acid chemically reacts with a base then it leads to the formation of salt and water.

For example, 3KOH + H_{3}PO_{4} \rightarrow K_{3}PO_{4} + 3H_{2}O

Here, KOH is a the base and H_{3}PO_{4} is an acid which on chemical reaction with each other leads to the formation of salt (K_{3}PO_{4}) and water (H_{2}O).

Thus, we can conclude that the given reaction is a neutralization reaction.

<h3>How are units labeled?</h3>

Use standardized unit abbreviations. For clarity, place units of before nonstandard units, such as (a) (units of a). When separating the components of a compound unit, use short spaces rather than hyphens, dots, or other symbols. For numbers on figure axes, use superscripts, multiplication signs, and powers of 10.

<h3>What is label in math means?</h3>

A graph labelling is the process of assigning labels, which are typically represented by integers, to the edges and/or vertices of a graph in the field of mathematics known as graph theory.
