What is the acidic an-hydride of phosphoric acid?
The acidic anhydride of phosphoric acid is pyrophosphoric acid (H4P2O7). It is formed by the condensation of two molecules of phosphoric acid (H3PO4) with the elimination of a water molecule.
Is phosphorus oxide acidic?
Phosphorus oxide can act as either acidic or basic, depending on the surrounding conditions. In water, phosphorus oxide can react with it to form phosphoric acid, making it acidic.
Is phosphorus oxide soluble in water?
No, phosphorus oxide is not soluble in water. It reacts with water to form phosphoric acid, but it does not dissolve in water as a pure compound.
What is the pH of phosphorus oxide?
Phosphorus oxide does not directly produce a pH value as it is not an acid or base in the traditional sense. However, when phosphorus oxide reacts with water, it forms phosphoric acid, which can result in a decrease in pH.
How does phosphoric acid affect metal oxides?
Phosphoric acid can react with metal oxides to form salts and water. The acid can dissolve the metal oxide by breaking down its lattice structure, leading to the formation of metal phosphate salts. This reaction can help in the removal of metal oxide layers from surfaces or in chemical processes involving metal oxides.

What is a balance equation for calcium oxide phosphoric acid?
3CaO + 2H3PO4 --> Ca3(PO4)2 + 3H2O
Is P2O5 an acidic oxide?
Yes, P2O5 is an acidic oxide. When it reacts with water, it forms phosphoric acid, which is a strong acid, making P2O5 acidic in nature.
What is the pH of phosphorus oxide?
Phosphorus oxide does not directly produce a pH value as it is not an acid or base in the traditional sense. However, when phosphorus oxide reacts with water, it forms phosphoric acid, which can result in a decrease in pH.

This reaction can help in the removal of metal oxide layers from surfaces or in chemical processes involving metal oxides.
What is the solvent for aluminium oxide?
The solvent for aluminium oxide is typically mineral spirits or a similar hydrocarbon-based solvent. These solvents are effective in dissolving and removing any residues of aluminium oxide.
What is the two salts when phosphoric acid react with zinc oxide?
There is only one salt being formed when an ACID reacts with an OXIDE, the other compound is water(!)So:phosphoric acid reacts with zinc oxideto form ....zinc phosphate and water
Is P4O10 acidic or basic?
P4O10 is acidic.
Is phosphorus oxide an amphoteric oxide?
No, phosphorus oxide is not an amphoteric oxide. It is a basic oxide, meaning it reacts with water to form a basic solution. Amphoteric oxides can act as both acidic and basic depending on the conditions.
What acid is used to remove rust?
Phosphoric acid is commonly used to remove rust as it reacts with iron oxide to dissolve rust and leave a clean metal surface. It is mild compared to other strong acids, making it a popular choice for rust removal on various surfaces.
