which of the following represents the hypochlorite ion?
clo₃⁻
clo⁻
clo₂⁻
clo₄⁻

Explanation:

1. For the naming of acids:

• $HNO_2$ is nitrous acid, a correct name as it is an acid with the nitrite - ion ($NO_2^-$).
• $HClO_3$ is chloric acid, which is correct as it contains the chlorate - ion ($ClO_3^-$).
• $H_2SO_3$ is sulfurous acid, correct as it contains the sulfite - ion ($SO_3^{2 - }$).
• $HBr$ is hydrobromic acid, not bromic acid. Bromic acid is $HBrO_3$.

1. For the hypochlorite ion:

• The hypochlorite ion has the formula $ClO^-$. $ClO_3^-$ is the chlorate ion, $ClO_2^-$ is the chlorite ion, and $ClO_4^-$ is the per - chlorate ion.

Answer:

First question: HBr, bromic acid
Second question: $ClO^-$
