Peroxodisulphuric acid

Consider the following statements for sodium thiosulphate:
(1) Sodium thiosulphate forms ${\mathrm{Na}}_2{\mathrm{SO}}_4$ with chlorine
(2) Sodium thiosuphate reacts with iodine to give sodium tetra thionate $\left({\mathrm{Na}}_2{ \mathrm{S}}_4{\mathrm{O}}_6\right)$ instead of ${\mathrm{Na}}_2{\mathrm{SO}}_4$
(3) It is used as fixer in black & white photography
(4) It is used as a volumetric reagent in the iodometric and iodimetric titrations
