Hãy cho biết sự biến đổi trong dãy \(HClO\,\, \to \,\,HCl{O_2}\,\, \to \,\,HCl{O_3}\,\, \) \(\to \,\,HCl{O_4}\) về tính axit, tính oxi hóa. Giải Tính axit tăng dần \(\eqalign{ & \buildrel {\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \over \longrightarrow \cr & HClO\,\,HCl{O_2}\,\,HCl{O_3}\,\,HCl{O_4} \cr & \buildrel {\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \over \longrightarrow \cr} \) Tính oxi hóa giảm dần.
