I metallic copper reacts with nitric acid but not with

Question

By reference to the Cu cycle lab experiment, identify the false statements among the following:

i) Metallic copper reacts with nitric acid but not with hydrochloric acid because CuCl₂ is insoluble in water whereas Cu(NO₃)₂ is soluble.

ii) When copper reacts with nitric acid, both nitrogen dioxide and hydrogen gas are produced.

iii) Copper does not react with hydrochloric acid but does with nitric acid because the latter is a stronger oxidizing agent.

iv) When Zn reacts with nitric acid, the only gas produced is hydrogen gas.

v) Metallic Zn is a stronger reducing agent than metallic copper.
