Question

List out some strong and weak electrolytes?

Answer 1

Electrolytes:

• The substances which have the ability to conduct electricity in their aqueous state or also called molten state, are known as electrolytes.
• Electrolytes are of two types; i.e Strong electrolytes and Weak electrolytes.

Strong electrolytes:

• Strong electrolytes have the tendency to fully dissolve in the aqueous solution.
• As electrolytes are completely ionized hence, are called strong electrolytes.
• Example:$\underset{(\mathrm{Sodium}\mathrm{chloride})}{\mathrm{NaCl}\left(\mathrm{aq}\right)}\to {\mathrm{Na}}^{+}\left(\mathrm{aq}\right)+{\mathrm{Cl}}^{-}\left(\mathrm{aq}\right)$, $\underset{(\mathrm{Calcium}\mathrm{Chloride})}{{\mathrm{CaCl}}_2\left(\mathrm{aq}\right)}\to {\mathrm{Ca}}^{2+}\left(\mathrm{aq}\right)+{\mathrm{Cl}}^{-}\left(\mathrm{aq}\right)$

Weak electrolytes:

• Weak electrolytes do not completely dissociate into the solvent.
• As the electrolytes get partially ionized hence, are called weak electrolytes.
• Examples: $\underset{(\mathrm{Acetic}\mathrm{acid})}{{\mathrm{CH}}_3\mathrm{COOH}\left(\mathrm{aq}\right)}\to {\mathrm{CH}}_3{\mathrm{COO}}^{-}\left(\mathrm{aq}\right)+{\mathrm{H}}^{+}\left(\mathrm{aq}\right)$,$\underset{(\mathrm{Ammonium}\mathrm{hydroxide})}{{\mathrm{NH}}_4\mathrm{OH}\left(\mathrm{aq}\right)}\to {\mathrm{NH}}_4^{+}\left(\mathrm{aq}\right)+{\mathrm{OH}}^{-}\left(\mathrm{aq}\right)$

Hence, above mentioned are the list of some strong and weak electrolytes.
