. Write the conjugate acid for each of the following bases:

a. PO 4 3-

b. IO 3 -

c. NO 3 -

d. NH 2 -

(a)

Interpretation:

The conjugate acid for the base should be determined.

Concept Introduction:

Acid is defined as a substance that gives hydrogen ion/s in the aqueous solution. Similarly, base is a substance that gives hydroxide ions in the aqueous solution. When an acid gives its hydrogen ion, conjugate base is formed and when a base gives its hydroxide ion, conjugate acid is formed.

For example, if HA is an acid, the reaction for formation of conjugate base will be as follows:

HA→H++A−

Here, A− is conjugate base.

Similarly, if BOH is a base, the reaction for formation of conjugate acid will be as follows:

BOH→B++OH−

Here, B+ is conjugate acid.

Thus, a conjugate base can accept hydrogen ion and conjugate base can accept hydroxide ion.

The given base is PO43−. Since, it is a base thus; it can accept hydrogen ion and conjugate acid of the given base can be formed as follows:

PO43−
