Verified step by step guidance1
Understand that perchloric acid is an oxyacid of chlorine, where chlorine is bonded to oxygen atoms and hydrogen is attached to the oxygen to form the acid.
Recall the naming convention for oxyacids: acids ending with '-ic' correspond to the oxyanion with the suffix '-ate'. The prefix 'per-' indicates the oxyanion has the highest number of oxygen atoms in the series.
Identify the perchlorate ion, which is ClO₄⁻, as the oxyanion related to perchloric acid.
Write the formula for perchloric acid by adding one hydrogen ion (H⁺) to the perchlorate ion (ClO₄⁻), resulting in HClO₄.
Confirm that the chemical formula for perchloric acid is \(HClO_4\), representing one hydrogen, one chlorine, and four oxygen atoms.
