The chemical equation serves as a roadmap, guiding us through the reaction's intricacies. On the left side of the equation, we encounter $NaOH$, which is none other than sodium hydroxide, a strong base. On the right side, we find $NaCH_3COO$, also known as sodium acetate, a salt, and $H_2O$, which is water. These products provide invaluable clues about the nature of the reaction and the identity of reactant X.

Unveiling the Nature of the Reaction: Acid-Base Neutralization

With the products in sight, we can discern the essence of the reaction: acid-base neutralization. In this fundamental chemical process, an acid and a base engage in a tête-à-tête, resulting in the formation of a salt and water. Sodium hydroxide ($NaOH$), our known reactant, is a quintessential base. Consequently, reactant X must be an acid to orchestrate this neutralization dance.

Exploring the Realm of Acids

Acids, the counterparts to bases, are substances that donate protons ($H^+$) or accept electrons. They play a pivotal role in countless chemical reactions, including the one we are investigating. To pinpoint the identity of reactant X, we must consider the acidic contenders presented in the answer choices.

Evaluating the Answer Choices: A Quest for the Acidic Partner

Let's now turn our attention to the answer choices, scrutinizing each to determine its suitability as reactant X:

A. $CH_3COOH$ B. $NH_4OH$ C. $H_3PO_4$ D. $H_2CO_3$

Option A: $CH_3COOH$ – Acetic Acid, the Prime Suspect

$CH_3COOH$, commonly known as acetic acid, immediately piques our interest. Acetic acid is a carboxylic acid, a class of organic acids characterized by the presence of a carboxyl group ($-COOH$). Carboxylic acids are renowned for their acidic properties, making acetic acid a prime suspect for reactant X.

Option B: $NH_4OH$ – Ammonium Hydroxide, a Base in Disguise

$NH_4OH$, ammonium hydroxide, raises a red flag. Ammonium hydroxide is a base, not an acid. As we established earlier, reactant X must be an acid to engage in neutralization with sodium hydroxide. Therefore, we can confidently eliminate option B from contention.

Option C: $H_3PO_4$ – Phosphoric Acid, a Potential Candidate

$H_3PO_4$, phosphoric acid, enters the fray as another potential candidate. Phosphoric acid is a mineral acid, known for its acidic nature. It could potentially react with sodium hydroxide in a neutralization reaction. However, we must delve deeper to ascertain its compatibility with the given products.

By understanding the behavior of strong bases, we can better predict the outcome of chemical reactions and identify the other reactants involved.

Step 3: Examining the Products: Sodium Acetate and Water

Now, let's examine the products of the reaction: sodium acetate ($NaCH_3COO$) and water ($H_2O$). Sodium acetate is the salt formed from the reaction of an acid and a base. The acetate ion ($CH_3COO^−$) is derived from acetic acid ($CH_3COOH$). This provides a crucial clue about the identity of reactant X. The formation of sodium acetate specifically points to acetic acid as the most likely candidate for reactant X. The acetate ion's presence in the product strongly suggests that acetic acid was the acid involved in the reaction. This connection between the products and the reactants is a key element in solving the puzzle.

A. $CH_3COOH$ B. $NH_4OH$ C. $H_3PO_4$ D. $H_2CO_3$

Eliminating the Base: Option B

First, we can eliminate option B, $NH_4OH$ (ammonium hydroxide), as it is a base, not an acid. Since we have determined that reactant X must be an acid, ammonium hydroxide is not a viable option. This initial elimination simplifies our task by reducing the number of possibilities we need to consider. By systematically ruling out incorrect options, we can narrow our focus and increase our chances of selecting the correct answer.

Assessing the Remaining Options: A, C, and D

Options A ($CH_3COOH$), C ($H_3PO_4$), and D ($H_2CO_3$) are all acids, so they remain potential candidates for reactant X. However, the formation of sodium acetate specifically suggests that acetic acid ($CH_3COOH$) is the most likely reactant. This step highlights the importance of considering the specific products formed in the reaction. While multiple acids could potentially react with sodium hydroxide, the formation of sodium acetate strongly suggests the involvement of acetic acid.

Step 5: Confirming the Identity of X: The Complete Reaction Equation

Finally, to confirm the identity of X, we can write out the complete reaction equation using acetic acid as reactant X:

$NaOH (aq) + CH_3COOH (aq) \rightarrow NaCH_3COO (aq) + H_2O (l)$

This equation shows the reaction between sodium hydroxide and acetic acid, producing sodium acetate and water. The equation is balanced, and the products match those given in the original incomplete reaction, thus confirming that reactant X is indeed acetic acid ($CH_3COOH$). This final step provides definitive confirmation of our deduction.
