Question

Write balanced chemical equation for dilute Nitric acid added to Copper turnings

Answer 1

1. Cold and dilute nitric acid (HNO₃)reacts with copper to form copper(II) nitrate and NO.
   $3\mathrm{Cu}+8{\mathrm{HNO}}_3(\mathrm{dil})\to 3\mathrm{Cu}{\left({\mathrm{NO}}_3\right)}_2+4{\mathrm{H}}_2\mathrm{O}+2\mathrm{NO}$
