# Give reasons Conc.HNO_3 can be transported in aluminium container.

11.22.    Give reasons

(i)  Conc. $H\! N\! O_{3}$  can be transported in aluminium container.

Conc. $H\! N\! O_{3}$  can be transported in an aluminium container because when it reacts with the aluminium it forms a thin layer of oxide on the surface. This layer renders aluminium passive.
