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. H3PO3 is a stronger acid than H3PO4 because it has fewer oxygens surrounding the central P atom. H2C2O4 is a stronger acid than HC2O4- because it has more acidic hydrogens. HI is a stronger acid than HCl because I atoms are larger than Cl atoms. H3AsO4 is a stronger acid than HAsO42- because it has more acidic H atoms. AsH3 is a stronger acid than HBr because As is larger than Br.Explanation / Answer
a)true HCl is a stronger acid than H2S because S and Cl are in the same row, and Cl is more electronegative
b)reason not correct
H3PO4 is a stronger acid than H3PO3 stronger than H3PO2. The reason here is like you said: has to do with electronegativit
