Understanding Neutralizing Reactions

Neutralizing reactions are a crucial aspect of chemistry, where an acid and a base react to form a salt and water. These reactions are essential in various fields, including chemistry, biology, and environmental science. In this article, we will focus on matching the salt with the acid and base used to form it in a neutralizing reaction, specifically for the salt $K_2SO_4$ .

The Reaction of $K_2SO_4$

To determine the acid and base precursors of $K_2SO_4$ , we need to understand the chemical equation for its formation. The reaction of $K_2SO_4$ can be represented as:

K_2SO_4 + 2H_2O \rightarrow 2KOH + H_2SO_4

From this equation, we can see that $K_2SO_4$ is formed from the reaction of potassium hydroxide (KOH) and sulfuric acid (H2SO4).

Analyzing the Options

Now, let's analyze the options provided to determine which one matches the acid and base precursors of $K_2SO_4$ .

Option A: NaBr

Sodium bromide (NaBr) is a salt formed from the reaction of sodium hydroxide (NaOH) and hydrobromic acid (HBr). This option does not match the acid and base precursors of $K_2SO_4$ .

Option B: $H_3PO_4$ and NaOH

Phosphoric acid (H3PO4) and sodium hydroxide (NaOH) react to form sodium phosphate (Na3PO4) and water. This option does not match the acid and base precursors of $K_2SO_4$ .

Option C: NaOH and HBr

Sodium hydroxide (NaOH) and hydrobromic acid (HBr) react to form sodium bromide (NaBr) and water. This option does not match the acid and base precursors of $K_2SO_4$ .

Option D: KOH and $H_2SO_4$

Potassium hydroxide (KOH) and sulfuric acid (H2SO4) react to form potassium sulfate ( $K_2SO_4$ ) and water. This option matches the acid and base precursors of $K_2SO_4$ .

Option E: $HPO_4$ and KOH

Monopotassium phosphate ( $HPO_4$ ) and potassium hydroxide (KOH) react to form potassium phosphate (K3PO4) and water. This option does not match the acid and base precursors of $K_2SO_4$ .

Conclusion

In conclusion, the correct answer is Option D: KOH and $H_2SO_4$ . This option matches the acid and base precursors of $K_2SO_4$ , as potassium hydroxide (KOH) and sulfuric acid (H2SO4) react to form potassium sulfate ( $K_2SO_4$ ) and water.
