Chapter 15, Problem 9PE

Order the following groups of acids from the weakest to the strongest: (a) HI, HF, HBr;

(b) ${\text{HCI, PH}}_{\text{3}}{\text{, H}}_{\text{2}}\text{S;}$ (c) ${\text{H}}_{\text{2}}{\text{Te, H}}_{\text{2}}{\text{O, H}}_{\text{2}}\text{Se;}$ (d) ${\text{AsH}}_3\text{ HBr}{\text{. H}}_2\text{Se;}$ (e) ${\text{HI, PH}}_3{\text{, H}}_2\text{Se}\text{.}$. (Hint: These are all binary acids.)
