Chapter 17, Problem 37c
Write the formula for the conjugate base of each acid. c. HCHO2
Verified step by step guidance1
Identify the acid given: HCHO₂, which is formic acid.
Recall that a conjugate base is formed by removing a proton (H⁺) from the acid.
Remove an H⁺ ion from HCHO₂. This involves removing one hydrogen atom and its positive charge.
After removing H⁺, the remaining species is CHO₂⁻.
Thus, the formula for the conjugate base of HCHO₂ is CHO₂⁻.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Conjugate Acid-Base Pairs
In acid-base chemistry, a conjugate acid-base pair consists of two species that differ by the presence of a proton (H+). When an acid donates a proton, it forms its conjugate base, while the base that accepts the proton becomes its conjugate acid. Understanding this relationship is crucial for identifying the conjugate base of any given acid.
Formic Acid (HCHO2)
Formic acid, or HCHO2, is a simple carboxylic acid that can donate a proton to form its conjugate base. Recognizing the structure of formic acid helps in determining its conjugate base, which is formed by removing a hydrogen ion (H+) from the acid. This process is fundamental in acid-base reactions.

Chemical Formula Representation
Chemical formulas represent the composition of a substance, indicating the types and numbers of atoms present. For acids and their conjugate bases, understanding how to manipulate these formulas by adding or removing protons is essential. This skill allows for the accurate identification of conjugate bases from their corresponding acids.
