1. These have higher molar conductivities at all concentrations.
2. λ°m values increase very slightly with dilution.
3. Degree of ionisation is very high at all concentration i.e., almost fully ionized.
4. Most of the salts like NaCl, KCl, NaNO3, BaCl2 and mineral acids like HCl, H2SO4, HNO3 and NaOH, KOH etc are common examples of strong electrolytes
1. These have much lower conductivities at high concentration.
2. λ°m values increase sharply with dilution.
3. Degree of ionisation is very low at high concentration and increases with dilution.
4. Salts like ammonium acetate, acetic acid, aq NH4OH, aqueous CO2 and organic acids and bases are common examples of weak electrolytes.
= 1.05 V – 0.0295 x log 80
= 1.05 V – 0.0295 x 1.9031
= 1.05 V – 0.056 = 0.99 V.
