The difference between a strong and weak acid is: 

• Strong acids stay intact in water weak acids don't 

• Strong acids are slippery weak acids aren't

• Strong acids break apart in water. Weak acids stay intact

• Weak acids break apart in water most of the time, strong acids do all of the time.
