Answer 1

$P_{2}O_{5}$ →$H_{3}PO_{4}$→$AlPO_{4}$

Answer 2

Chemical Reaction: Oxide of Phosphorus(V) to Phosphoric Acid to Salt

When oxide of phosphorus(V) reacts with water, it forms phosphoric acid. Phosphoric acid can then react with a base to form a salt.

The chemical equations for these reactions are as follows:

1. Oxide of Phosphorus(V) to Phosphoric Acid: - The reaction of oxide of phosphorus(V) with water forms phosphoric acid. - The balanced chemical equation for this reaction is: ``` P4O10 + 6H2O → 4H3PO4 ``` - This reaction is also known as the hydrolysis of phosphorus pentoxide.

2. Phosphoric Acid to Salt: - Phosphoric acid can react with a base to form a salt. - The general equation for this reaction is: ``` H3PO4 + 3NaOH → Na3PO4 + 3H2O ``` - In this reaction, phosphoric acid (H3PO4) reacts with sodium hydroxide (NaOH) to produce sodium phosphate (Na3PO4) and water.

These chemical reactions are fundamental in understanding the transformation of oxide of phosphorus(V) to phosphoric acid and subsequently to a salt.
