when naming an acid comprised of an anion such as perchlorate, the prefix per- is retained in the <modified anion name>. thus, the acid comprised of the perchlorate anion clo₄⁻ would be called ____________ and has the formula hclo₄. hypochlorous acid hypochloric acid perchloric acid perchlorous acid

when naming an acid comprised of an anion such as perchlorate, the prefix per- is retained in the <modified anion name>. thus, the acid comprised of the perchlorate anion clo₄⁻ would be called ____________ and has the formula hclo₄. hypochlorous acid hypochloric acid perchloric acid perchlorous acid

Answer

Brief Explanations:

When an acid is formed from a per - anion like perchlorate ($ClO_4^-$), the prefix 'per -' is kept in the acid name. The acid with formula $HClO_4$ is named based on the perchlorate anion. Hypochlorous acid is $HClO$, hypochloric acid is not a standard name for a common acid, and perchlorous acid is $HClO_3$.

Answer:

C. perchloric acid
