Answer to Problem 40QAP

The complete the acid −base reaction by written missing strong acid and strong base is as follows:

H2SO4 (aq) +2KOH (aq)  K2SO4 (aq) + 2 H2O (l)Acid                 Base                 Salt                   water.

Explanation of Solution

All strong acid and strong bases are the example of strong electrolytes while all weak acid and weak bases behaves weak electrolytes.

The strong bases are also strong electrolytes because they are fully ionize in the solution for example sodium hydroxide

NaOHH2ONa+ + OH

All strong acids are fully ionize thus they are strong electrolytes. For example hydrochloric acid:

HClH2OH+ + Cl

The net ionic process or equation of any strong acid with strong base will from salt and water because both strong acids and bases present as fully ionize form in both sides for example the reaction of strong acid, hydrochloric acid with strong base sodium hydroxide is as follows:

NaOH (aq) + HCl(aq)  NaCl (aq) + H2O (l)
