Introduction
In chemistry, acids and bases play a crucial role in various chemical reactions. The concept of acid-conjugate base pairs is essential in understanding the behavior of acids and bases in different environments. In this article, we will discuss the reaction between ammonium ion (NH4+) and water (H2O) to identify the acid-conjugate base pair.
The Reaction
Consider the reaction below:
In this reaction, the ammonium ion (NH4+) reacts with water (H2O) to form ammonia (NH3) and hydronium ion (H3O+). This reaction is a classic example of an acid-base reaction.
Identifying the Acid-Conjugate Base Pair
To identify the acid-conjugate base pair, we need to understand the definition of an acid and a base. An acid is a substance that donates a proton (H+), while a base is a substance that accepts a proton. In the reaction above, the ammonium ion (NH4+) donates a proton to form ammonia (NH3), which is a base. On the other hand, the hydronium ion (H3O+) accepts a proton to form water (H2O), which is an acid.
Analyzing the Options
Now, let's analyze the options given:
A. { NH_4^{+} $}$ and { NH_3 $}$
In this option, the ammonium ion (NH4+) is the acid, and ammonia (NH3) is the conjugate base. This is a correct acid-conjugate base pair.
B. { NH_4^{+} $}$ and { H_3O^{+} $}$
In this option, the ammonium ion (NH4+) is the acid, and the hydronium ion (H3O+) is the conjugate acid. This is not a correct acid-conjugate base pair.
C. { H_2O $}$ and { H_3O^{+} $}$
In this option, water (H2O) is the acid, and the hydronium ion (H3O+) is the conjugate acid. This is not a correct acid-conjugate base pair.
Conclusion
In conclusion, the acid-conjugate base pair in the reaction between ammonium ion (NH4+) and water (H2O) is the ammonium ion (NH4+) and ammonia (NH3). This is because the ammonium ion (NH4+) donates a proton to form ammonia (NH3), which is a base.
Why Acid-Conjugate Base Pairs are Important
Acid-conjugate base pairs are essential in understanding various chemical reactions, including acid-base reactions. In acid-base reactions, the acid donates a proton to form a conjugate base, while the base accepts a proton to form a conjugate acid. Understanding acid-conjugate base pairs helps us predict the behavior of acids and bases in different environments.
Types of Acid-Conjugate Base Pairs
There are two types of acid-conjugate base pairs: strong acid-strong base pairs and weak acid-weak base pairs. Strong acid-strong base pairs involve the complete dissociation of the acid and base, resulting in the formation of a conjugate base and a conjugate acid. Weak acid-weak base pairs involve the partial dissociation of the acid and base, resulting in the formation of a conjugate base and a conjugate acid.
Examples of Acid-Conjugate Base Pairs
Some examples of acid-conjugate base pairs include:
- HCl (hydrochloric acid) and Cl- (chloride ion)
- H2SO4 (sulfuric acid) and HSO4- (hydrogen sulfate ion)
- NH4+ (ammonium ion) and NH3 (ammonia)
Conclusion
In conclusion, acid-conjugate base pairs are essential in understanding various chemical reactions, including acid-base reactions. Understanding acid-conjugate base pairs helps us predict the behavior of acids and bases in different environments. By analyzing the reaction between ammonium ion (NH4+) and water (H2O), we can identify the acid-conjugate base pair as the ammonium ion (NH4+) and ammonia (NH3).

Q: How do acid-conjugate base pairs affect the pH of a solution?
A: Acid-conjugate base pairs can affect the pH of a solution by either increasing or decreasing the concentration of hydrogen ions (H+).

A: Acid-conjugate base pairs are essential in the formation of buffer solutions. A buffer solution is a mixture of a weak acid and its conjugate base, which can resist changes in pH. The acid-conjugate base pair in a buffer solution can accept or donate protons to maintain a stable pH.
Q: How do acid-conjugate base pairs affect the solubility of a substance?
A: Acid-conjugate base pairs can affect the solubility of a substance by either increasing or decreasing its solubility. If the acid is a strong acid, it can increase the solubility of a substance by donating protons and increasing the concentration of hydrogen ions. If the acid is a weak acid, it can decrease the solubility of a substance by accepting protons and decreasing the concentration of hydrogen ions.
