Solution

The correct option is B Water and nitrogen dioxide
$C u (s) + H N O_{3} (a q) \to C u (N O_{3})_{2} (a q) + H_{2} O + N O_{2} (g)$

Cupric nitrate $(C u (N O_{3})_{2})$ along with water and nitrogen dioxide is obtained on the copper test. These products are obtained due to the oxidising nature of nitric acid.

Q. 1.375 g of cupric oxide was reduced by heating in a current of hydrogen and the mass of copper that remained was 1.098 g . In another experiment 1.179 g copper was dissolved in nitric acid and the resulting copper nitrate was converted into cupric oxide . The mass of cupric oxide formed was 1.476 g . Show that these results illustrate the law of constant composition.
