Skill 16.6 Identifying properties of strong and weak electrolyte solutions 

Particles in solution are free to move about and collide with each other, vastly increasing the likelihood that a reaction will occur compared with particles in a solid phase. Aqueous solutions may react to produce an insoluble substance that will fall out of solution as a solid or gas precipitate in a precipitation reaction. Aqueous solution may also react to form additional water, or a different chemical in aqueous solution. 

Strong acids and bases are strong electrolytes, and weak acids and bases are weak electrolytes, so strong acids and bases completely dissociate in water, but weak acids and bases do not. 

Example HCI(aQ) + H20(/) H O aq) + C aq) goes to completion because HCl is a strong acid. The acids in the previous examples were all weak. 

Acid and base strength is not related to safety. Weak acids like HF may be extremely corrosive and dangerous. The most common strong acids and bases are listed here
