A strong acid dissociates almost completely in solution, that is to say the solution is ionic particles charged either positively, or negatively. This allows an electric current to pass strongly...
HI is a strong electrolyte. Strong acids, bases, and salts with high solubility make the best electrolytes.
Strong Acids and Bases are strong electrolytes weak acids and bases are weak electrolytes
If you mean strong acids then yes, strong acids are strong electrolytes.
Because they dissociate completely in water to produce H+ ions in solution.
