Describe the type of electrolytes that acids and bases make and what that has to do with whether they are weak or strong
What are: strong acids and bases dissociate into their ions fully (salts do this as well) and are therefore electrolytes (good conductors of electricity, bulb glows brightly).
Weak acids and bases do not dissociate fully therefore they do not fully dissociate into their ions fand are therefore poor electrolytes (moderate conductors of electricity, bulb glows dimly).
