Question

How Do You Extract Highly Reactive Metals?

Answer 1

Reactive metal-

Reactive metals react with acids, water, and mineral acid. As series progress from top to bottom, the reactivity of metal increases and loses electrons to form a positive ion.

Extraction of highly reactive metals-

Electrolytic reduction is used to extract metals with high reactivity from their ores such as sodium, magnesium, and calcium.

Electrolytic reduction:

This electric current passes through molten or dissolved ionic substances, causing electrodes to chemically react and material to decompose.

Metal is collected at the cathode. some metals such asK, Na, and Al are obtained through an electrolytic reduction process.

As electric current passes through molten sodium chloride, sodium metal is deposited over the cathode

$$\begin{gathered} {\mathrm{Na}}^{+}+{\mathrm{e}}^{-}\to \mathrm{Na} \\ 2\mathrm{Cl}+{\mathrm{e}}^{-}\to {\mathrm{Cl}}_2 \\ 2\mathrm{NaCl}\to 2\mathrm{Na}+{\mathrm{Cl}}_2 \end{gathered}$$
