Rank the following 0.100 M solutions in order of increasing H3O+ concentration:
HF, Ka = 6.3 × 10−4; HCN, Ka = 6.2 × 10−10; HOCl, Ka = 4.0 × 10−8

HF < HCN < HOCl

HCN < HOCl < HF

HOCl < HCN < HF

HF < HOCl < HCN

HOCl < HF < HCN

An acid gets its traits from the hydrogen atoms of its molecules. sturdy acids have weakly certain hydrogen atoms, and the molecules easily break away from them in solution. How many of these hydrogen atoms dissociate and form hydrogen ions determines the electricity of an acid

The larger the Kₐ value = to the stronger the acid.

comparing ka value

6.2 × 10⁻¹⁰ < 4.0 × 10⁻⁸ < 6.3 × 10⁻⁴

⇒ HCN < HOCl < HF

What reasons acid power?

The relative power of an acid may be anticipated primarily based on its chemical structure. In trendy, an acid is stronger while the H–A bond is greater polar. Acidity is also greater while the H–A bond is weaker and when the conjugate base, A⁻, is greater stability.

What's the distinction between acidic energy and acidity?

Acidic electricity and acidity are contrary phrases. Acidic electricity represents the ability of an acid to launch H+ ions. more the tendency to launch H+ ions in aqueous solution, extra is the acidic power. A strong acid will have better dissociation regular than a vulnerable acid.
