Which of the following acids is the strongest? the acid is followed by its ka value. which of the following acids is the strongest? the acid is followed by its ka value. hf, 3.5 × 10-4 hcooh, 1.8 × 10-4 hclo2, 1.1 × 10-2 hcn, 4.9 × 10-10 hno2, 4.6 × 10-4

chlorous acid HClO₂

Explanation:

The Ka is the acidity constant and it tells you about the acidity strength of a compound. If the value of Ka is high the compound is a strong acid. If the value of Ka is low the compound is a weak acid.  

The problem gives us the following compounds with the Ka values:

HF, 3.5 × 10⁻⁴

HCOOH, 1.8 × 10⁻⁴  

HClO₂, 1.1 × 10⁻²  

HCN, 4.9 × 10⁻¹⁰

HNO₂, 4.6 × 10⁻4

The chlorous acid HClO₂ have the highest Ka, 1.1 × 10⁻², so this one is the strongest acid.
