# . Write the conjugate base for each of the following acids: a. H2S b. HS- c. NH3 d. H2SO3

Interpretation Introduction

(a)

Interpretation:

The conjugate base for the acid 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 a 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:

HAH++A

Here, A is conjugate base.

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

BOHB++OH

Here, B+ is conjugate acid.

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

Explanation

The given acid is H2S. Since, it is an acid thus; it can donate hydrogen ion and conjugate base of the given acid can be formed as follows:

H2S&#
