Question

What is the anion found in phosphoric acid?

Answer 1

...contains the sulfate anion (SO42−) and is called sulfuric acid; H3PO4 contains the phosphate anion (PO43−) and is called phosphoric acid; and HC2H3O2, which contains the acetate ion (C2H3O2−), is c... Phosphoric acid (H3PO4) has three hydrogen atoms, all of which are replaceable by a metal.

Answer 2

Answer : The anion found in phosphoric acid is, phosphate ion $(PO_4^{3-})$

Explanation :

Phosphoric acid is a weak acid. The formula of phosphoric acid is, $H_3PO_4$.

Phosphoric acid is formed when three molecules of hydrogen combine with one molecule of phosphate molecule by criss-cross method.

The formula of phosphate ion is, $PO_4^{3-}$ and it is a polyatomic ion composed of two or more atoms that are covalently bonded.

Hence, the anion found in phosphoric acid is, phosphate ion $(PO_4^{3-})$
