Select the correct statement: (1) HSO5−\mathrm{HSO_5^-} ion has one S−O−H\mathrm{S-O-H} linkage. (2) The number of B−O−B\mathrm{B-O-B} linkages in borax is equal to the number of P−O−P\mathrm{P-O-P} linkages in P4O10\mathrm{P_4O_{10}}. (3) The hybridization of both sulfur atoms in H2S2O5\mathrm{H_2S_2O_5} (pyrosulfurous acid) is the same, but their oxidation states are different. (4) Tetrapolyphosphoric acid has four P−O−P\mathrm{P-O-P} and no P−P\mathrm{P-P} linkage.
