Question

Give scientific reason : Hydrogen gas is not evolved when copper reacts with dilute H2SO4 ​

Answer 1

$\huge\boxed{\texttt{\fcolorbox{aqua}{grey}{Answer}}}$

This is so because copper lies below in the series than hydrogen. ... Thus, it will not easily replace hydrogen from its chemical reaction and evolve hydrogen gas. The chemical equation for the reaction of copper and sulfuric acid follows: Thus, this is so because copper lies below in the series than hydrogen.

Answer 2

as we know that H2 s o4 contains hydrogen in it and hydrogen is more reactive than copper so there is no reaction when copper reacts with dilute H2 s o4 and others hydrogen gas is not evolved because hydrogen cannot be replaced by copper
