Expert Answers

Strong base completely ionizes in the solution. Meaning, the dissociation to OH- in the solution is complete. 

BOH    --->  B+  +  OH-

The ionization of strong base in water produces hydroxide ion.

Let us use NaOH or commonly known as Sodium hydroxide. Generally a base has a pH below 7, neutralizes acid and turns red litmus paper to blue. This also means that in a solution (in water) NaOH produces Hydroxide ions (OH- ions).

The chemical equation for the dissociation of Sodium hydroxide (NaOH) in the solution can be written as:

NaOH (s) + H2O ---> Na+  +   OH-

Provide equation for ionization of a strong acid in water solution?

Strong acid completely ionizes in the solution. Meaning, the dissociation of H+ in the solution is complete. 

HA  +  H2O    --->  H3O+  +  A-

The ionization of strong acid in water produces hydronium ion and a conjugate base,

Let us use HCl or commonly known as Hydrochloric acid. As the name suggests, this compound is an acid. Generally an acid, is a proton donor, has a pH below 7, neutralizes base and turns blue litmus paper to red. This also means that in a solution (in water) HClO4 produces Hydronium ions (H3O+ ions).

The chemical equation for the dissociation of Hydrochloric (HCl) in the solution can be written as:

HCl (aq) + H2O ---> H3O+   +   Cl-       

 **hydronium ions can be represented as H3O+ or simply H+.

Provide equation for ionization of a weak base in water solution?

Ionization of weak bases is an equilibrium process wherein weak bases is partially dissociated in the solution thus making the pH lower than that of strong bases with similar concentration. The general equation for the dissociation of weak bases in aqueous media can be written as:

B +  H2O   <--->  BH+  + OH-

The chemical equation of weak base produces hydroxide ions (OH-) and the conjugate acid of the weak base. Double arrow signifies equilibrium. An example of a weak base is NH3. In aqueous solution, NH3 ionizes into:

NH3 + H2O   ---> NH4+  +   OH-
