Question
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.
Hint:
Strong acids ionizes completely.
The correct answer is: Strong acids break apart in water. Weak acids stay intact
An acid is said to be strong if it dissociates or ionizes completely in a solution. That means, it is able to give the largest number of H+ ions or protons when mixed in a solution. These ions are the charged particles. Since a strong acid donates a greater number of ions as it breaks down, or ionizes completely, weak acids doesn't dissociate completely.
The difference between a strong and weak acid is strong acids break apart in water, weak acids stay intact.
