D. Hydrogen phosphotetroxide
E. Phosphorous acid
What is the name of H₃PO₄?
A. None of the above
B. Hydro phosphoric acid
C. Phosphoric acid
D. Hydrogen phosphotetroxide
E. Phosphorous acid
Answer:
The chemical name for PO₄⁻³ is Phosphate ion.
When it comes to naming ionic compounds, it is important to understand the chemical composition of each ion involved. Ionic compounds are formed when positively and negatively charged ions come together to create a stable compound.
In the case of PO₄⁻³, it is known as the Phosphate ion. The Phosphate ion is a polyatomic ion composed of one phosphorus atom bonded to four oxygen atoms. This combination results in a negatively charged ion with a charge of -3. Knowing the chemical name for each ion is crucial in naming ionic compounds correctly.
For H₃PO₄, its name is Phosphoric acid. Phosphoric acid is a common and important chemical compound used in various industries such as fertilizers, detergents, and food and beverage. It is also an essential component in the production of phosphates, which are vital for plant growth.
