(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. H2SO4 is a stronger acid than HSO4- because it has more acidic H atoms. HI is a stronger acid than HCl because I atoms are larger than Cl atoms. H2PO4- is a stronger acid than H3PO4 because it has more charge (is more unstable). HIO4 is...

(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. HClO3 is a stronger acid than HClO4 because it has fewer oxygens surrounding the central Cl atom. H2Se is a stronger acid than H2S because Se atoms are larger than S atoms. H2PO4- is a stronger acid than HPO42- because it has more acidic H atoms....
