Select all of the correct statements about the relative acid strengths of pairs

Question

Select all of the correct statements about the relative acid strengths of pairs of acids from the choices below. HCI is a stronger acid than H2S because Cl is more electronegative than S. HI is a stronger acid than HCI because I atoms are larger than Cl atoms. HIO is a stronger acid than HIO_4 because it has fewer oxygens surrounding the central I atom. H_2PO_4^- is a stronger acid than H_3PO_4 because it has more charge (is more unstable). PH_3 is a stronger acid than H_2S because P is larger than S. H_2AsO_4^- is a stronger acid than H_3AsO_4 because it has more charge (is more unstable).

Explanation / Answer

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

HI is a stronger acid than HCl because I atoms are larger than Cl atom.

note : if the electronegativity difference is less between H-atom and other , acidity increases , but not for HF
