The solution that will conduct the highest amount of electricity is?
- 0.5 mol dm-3 of hydrochloric acid
-
2.0 mol dm-3 of hydrochloric acid
- 0.5 mol dm-3 ethanoic acid
- 2.0 mol dm-3 ethanoic acid
The correct answer is: B
Explanation
Hence, for most aqueous solutions, the more ions, the higher the conductivity.
Strong electrolytes ionize completely e.g strong acid, strong bases and some salts
While weak electrolytes ionize only partially e.g CH3COOH is regarded as acetic acid.
It is a weak electrolyte. Acetic acid is regarded as weak electrolyte because its dissociation constant is low.
