Vedclass · Answer

(A) The reaction of zinc $(Zn)$ with nitric acid $(HNO_{3})$ depends on the concentration of the acid.$1$. With dilute $HNO_{3}$,zinc reacts to produce nitrous oxide $(N_{2}O)$:$4Zn   10HNO_{3} (	ext{dilute}) ightarrow 4Zn(NO_{3})_{2}   5H_{2}O   N_{2}O$$2$. With concentrated $HNO_{3}$,zinc reacts to produce nitrogen dioxide $(NO_{2})$:$Zn   4HNO_{3} (	ext{conc.}) ightarrow Zn(NO_{3})_{2}   2H_{2}O   2NO_{2}$Therefore,the products are $N_{2}O$ and $NO_{2}$ respectively.

The reaction of zinc with dilute and concentrated nitric acid,respectively,produces:
