Question

Write an ionic equation for a reduction of Aluminium ion to Aluminum atom

Answer 1

The ionic equation for a reduction of Al ion to Al atom is as follows-

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

• Aluminium is an alkaline earth metal. It has an atomic number of 13. It generally exists as $Al^{+3}$ ion in its ionic state.
• To convert the Al ion to an Al atom we need to add three electrons to the Al ion.
• Hence the ionic equation for a reduction of Al ion to Al atom is as follows-
• $Al^{+3}+3e^-\rightarrow Al$.
