Which is the balanced single displacement reaction between Aluminum (Al3+) and Copper Sulfate (Cu2+(SO4)2-)

Aliun [14]

Answer:

The balanced single displacement reaction between aluminum and copper sulphate is as follows.

$2Al(s)+3CuSO_{4}(aq)\rightarrow Al_{2}(SO_{4})_{3}(aq)+3Cu(s)$

Explanation:

The given ions are as follows.

$Al^{3+}$ - Aluminium ion and copper sulfate ion.

Single displacement reaction occurs one element replaces another element.

Hence, the balanced chemical reaction is as follows.

$2Al(s)+3CuSO_{4}(aq)\rightarrow Al_{2}(SO_{4})_{3}(aq)+3Cu(s)$

Oxidation half reaction:

$Al\rightarrow Al^{3+}+3e^{-}$

Aluminium loses three electrons.

Reduction half reaction:

$Cu^{2+}+2e^{-}\rightarrow Cu(s)$

Copper gain three electrons.

How could you increase the atomic number?

TEA [102]

The increase in the number of atoms allows the strong positive charge of the nucleus to increase. Thus, due to the number of positive protons increasing in the nucleus, the positive charge increases. On the negatively charged electron cloud, the high positive charge of the nucleus has a strong tug.
