Verified step by step guidance1
Understand the concept of conjugate acids and bases: A conjugate acid is formed when a base gains a proton (H^+). Conversely, a conjugate base is formed when an acid loses a proton.
Identify the base in the problem: The base given is CO3^2- (carbonate ion).
Determine the process of forming a conjugate acid: To form the conjugate acid of CO3^2-, add a proton (H^+) to the base.
Write the chemical equation for the addition of a proton: CO3^2- + H^+ → HCO3^-.
Recognize the resulting species: After adding a proton to CO3^2-, the resulting species is HCO3^- (bicarbonate ion), which is the conjugate acid of the base CO3^2-.
