Question

(a) Select all of the correct statements about the relative acid strengths of pairs of acids from the choices below.


HCl is a stronger acid than H2S because Cl is more electronegative than S.

HClO is a stronger acid than HClO2 because it has fewer oxygens surrounding the central Cl atom.

H2AsO4- is a stronger acid than HAsO42- because it has more acidic H atoms.

HF is a stronger acid than NH3 because F is more electronegative than N.

HF is a stronger acid than HBr because F is more electronegative than Br.

NH3 is a stronger acid than PH3 because N is more electronegative than P.



Explanation / Answer

*HCl is a stronger acid than H2S because Cl is more electronegative than S.

* H2AsO4- is a stronger acid than HAsO42- because it has more acidic H atoms.

* HF is a stronger acid than NH3 because F is more electronegative than N.
