A strong acid OR base is one that:

Question 11 options:

A. dissociates 50%, producing 50% H+ and 50% OH- in solution; this makes it conduct electricity 50%.

B. completely (100%) dissociates, producing a significant amount of H+ and OH- ions in solution, making it conduct electricity well.

C. dissociates just enough to conduct electricity weakly.

D. only partially dissociates, producing only a few H+ and OH- ions in solution, making it a weak conductor of electricity.

completely (100%) dissociates, producing a significant amount of H+ and OH- ions in solution, making it conduct electricity well.

Explanation:

A strong acid is one that ionizes or dissociate completely in water to yield its hydrogen ion (H+) as the only positively charged ion.

For example: Hydrochloric acid (HCl) dissociates completely in water to give hydrogen ion and chlorine ion

HCl(aq) --> H+(aq) + Cl-(aq)

A strong base, on the other hand, dissociates completely in water to yield an hydroxyl ion (OH-) as the only negatively charged ion. A good example is Sodium hydroxide NaOH

NaOH (aq) --> Na+(aq) + OH-(aq)

And since mobile and charged ions help transmit electric current, a strong acid or base produces significant amount of H+ and OH- ions that conduct electricity well.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
