Question

Copper reacts with dilute ${H_2}S{O_4}$ to form.
A)$CuS{O_4}$
B)$C{u_2}S{O_4}$
C)$Cu$
D) None of the above.

Answer 1

Hint: We have to know that the copper is a synthetic component with the symbol \[Cu\] and atomic number of \[29\]. It is a delicate, pliant, and pliable metal with high warm and electrical conductivity. A newly uncovered surface of unadulterated copper has a pinkish-orange tone.

Complete step by step answer:
We have to remember that the copper is beneath hydrogen in the reactivity arrangement of metals, so it can't dislodge hydrogen from dilute sulphuric acid. It anyway responds with conc. Sulphuric corrosive to free sulfur dioxide gas.
Therefore, the option D is correct.
$Cu + dil.{H_2}S{O_4} \to {\text{No reaction}}$
Copper doesn't respond with water, yet it does gradually respond with environmental oxygen to frame a layer of earthy colored dark copper oxide which, dissimilar to the rust that structures on iron in wet air, shields the fundamental metal from additional consumption. A green layer of verdigris (copper carbonate) can frequently be seen on old copper structures, for example, the material of numerous more seasoned buildings and the Statue of Liberty. Copper discolors when presented to some sulfur mixes, with which it responds to frame different copper sulfides.

Note: We know that Copper is called cupric. The chemical Formula of copper is \[Cu\].
We can define valency as the combining capacity of an element. The Electron configuration of copper \[\left[ {Ar} \right]3{d^{10}}4{s^1}\]. Thus, the valency of cupric is 2. Copper is utilized as a channel of warmth and power, as a structure material, and as a constituent of different metal compounds, for example, authentic silver utilized in adornments, cupronickel used to make marine equipment and coins, and constantan utilized in strain checks and thermocouples for temperature estimation.
