Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Acid-Base Reactions

Acid-base reactions involve the transfer of protons (H+) between species. In this context, an acid donates a proton to a base, which accepts it. Understanding this concept is crucial for writing the correct chemical equation, as it helps identify the reactants and products based on their roles in the reaction.

Bronsted-Lowry Acid

According to the Bronsted-Lowry theory, an acid is defined as a substance that donates protons in a reaction. In the given question, H2C6H7O5- acts as a Bronsted-Lowry acid when it donates a proton to water, leading to the formation of its conjugate base and hydronium ion. Recognizing this classification is essential for accurately depicting the reaction.
