(a) Acids as well as bases ionize in water. Name the ions produced by each in water.

(b) If we have hydrochloric acid and acetic acid of equal concentration, which will be a stronger acid and why?

(c) How will the concentration of hydrogen ions affected if an acid is diluted?

Expert Answer:

(a) Acids ionize in water to produce positively charged hydrogen ions (H+).
     Bases ionize in water to produce negatively charged hydroxide ions (OH-).

(b) Hydrochloric acid will be a stronger acid than acetic acid because it completely ionizes in water to produce a large amount of hydrogen ions. On the other hand, acetic acid partially ionizes in water to produce only a small amount of hydrogen ions.

(c) The concentration of hydrogen ions decreases if an acid is diluted by adding more and more water to it.
