The Name of Acid with Formula H3PO4

Explanation:

Phosphoric acid is the correct answer for the acid with the formula H3PO4. The formula H3PO4 corresponds to phosphoric acid which is a common mineral acid used in various industries such as food and beverage, pharmaceuticals, and fertilizers.

The formula H3PO4 indicates that the acid contains one phosphorus atom, four oxygen atoms, and three hydrogen atoms. The naming convention for acids is based on the composition of the compound. In the case of H3PO4, the presence of phosphorus and oxygen determines the name of the acid as phosphoric acid.

It's important to note that acids are substances that ionize in water to release hydrogen ions. The H3PO4 molecule dissociates in water to release H+ ions, leading to the characteristic acidic properties of the compound.

Therefore, the correct name for the acid with the formula H3PO4 is phosphoric acid.
