Question

How is a strong electrolyte different from a weak electrolyte?

Answer 1

Strong electrolytes are compounds which dissociate completely in their aqueous or fused state. It allows electricity to flow through them. e.g. all strong acids and alkalis.
Weak electrolytes are chemical compounds which dissociate partially in their aqueous or fused state. They are not good conductors of electricity, e.g. weak acids like carbonic acid, weak alkalis like ammonium hydroxide.
