What else can I help you with?
Is it a copper OR zinc penny that dissolves in phosphoric acid?
A zinc penny would dissolve in phosphoric acid, not a copper penny. Zinc reacts with phosphoric acid to form zinc phosphate and hydrogen gas. This reaction does not occur with copper, as copper is a more stable metal and does not react with phosphoric acid in the same way.
What is H3PO4?
H3PO4 is the chemical formula for phosphoric acid, a weak acid commonly used in food and beverage production, as well as in rust removal and metal cleaning. It is a key ingredient in fertilizers, detergents, and other industrial processes.
How does temperature affect phosphoric acid?
high temperature can make phosphoric acid be a cryztal i ever do this experiment, after i make phosphoric acid and then i burn it until the temperature is 100C, phosphoric acid had been cryztal when the temperature decrease.
Why can phosphoric acid prevent rusting?
Phosphoric acid can prevent rusting by forming a protective layer of iron phosphate on the surface of metal. This layer acts as a barrier, preventing oxygen and water from reaching the metal surface and causing it to corrode. Additionally, phosphoric acid can also act as a mild acid to remove existing rust and corrosion from metal surfaces.
What two substances can react with hydrochloric acid to form salt?
Two substances that can react with hydrochloric acid to form salt are metal oxides and metal carbonates. When metal oxides react with hydrochloric acid, they form metal chloride and water. When metal carbonates react with hydrochloric acid, they form metal chloride, carbon dioxide, and water.
Is it a copper OR zinc penny that dissolves in phosphoric acid?
A zinc penny would dissolve in phosphoric acid, not a copper penny. Zinc reacts with phosphoric acid to form zinc phosphate and hydrogen gas. This reaction does not occur with copper, as copper is a more stable metal and does not react with phosphoric acid in the same way.
Are metal oxides neutral?
Metal oxides can be basic, acidic, or amphoteric depending on the metal and the oxidation state of the metal ion. Basic metal oxides react with acid to form a salt and water, while acidic metal oxides react with base to form a salt and water. Amphoteric metal oxides can act as both an acid and a base depending on the reaction conditions.

How can you use metal oxides to distinguish strong acid from weak acid?
Metal oxides can be used to distinguish strong acids from weak acids based on their reactivity. Strong acids, like hydrochloric acid, will react vigorously with metal oxides, leading to the formation of metal salts and releasing hydrogen gas. In contrast, weak acids, such as acetic acid, do not react significantly with metal oxides due to their lower dissociation in solution. Thus, observing the intensity of the reaction can help identify whether an acid is strong or weak.
What two substances can react with hydrochloric acid to form salt?

Is poly phosphoric acid different from phosphoric acid?
I don't think so.poly phosphoric acid and phosphoric acid have same moleculer structure.http://harvestchem.iblogger.org
What is the acid name H3PO4?
phosphoric acid
Why can Phosphoric acid be used to remove rust from a metal surface?
Phosphoric acid reacts with rust to form iron phosphate, which can be easily removed from the metal surface. The acid also acts as a passivator, which helps prevent further rusting by forming a protective layer on the metal.
What is the reaction of phosphoric acid with nitric acid?
phosphoric acid
What is the word equation for the reaction between acids and metal oxides?
The general word equation for the reaction between acids and metal oxides is: acid + metal oxide -> salt + water. The specific salt formed depends on the acid and metal oxide involved in the reaction.
