Question

select the correct answer. what is the name of h₃po₄? a. hydrophosphoric acid b. hydrophosphorous acid c. hydrophosphic acid d. phosphorous acid e. phosphoric acid

Explanation:

The compound $H_3PO_4$ is named phosphoric acid. The prefix "hydro -" is used for binary acids (acids with hydrogen and a non - oxygen element only). Since $H_3PO_4$ contains oxygen, the "hydro -" prefix is not used. "Phosphorous acid" refers to $H_3PO_3$.

Answer:

E. phosphoric acid
