illustrate how copper metal can give different products on reaction with $H N O_{3}$ .

Solution

The products of the reaction of copper with $H N O_{3}$ depends upon the concentration of $H N O_{3}$ used

(i) Copper metal reacts with dilute $H N O_{3}$ to form nitrogen (II) oxide (NO).

$3 C u + 8 H N O_{3} (d i l u t e) \to 3 C u (N O_{3})_{2} + 2 N O + 4 H_{2} O$

(ii) Copper metal reacts with conc. $H N O_{3}$ to form nitrogen (IV) oxide or nitrogen dioxide $N O_{2}$ .

$C u + 4 H N O_{3} (c o n c .) \to C u (N O_{3})_{2} + 2 N O_{2} + 2 H_{2} O$
