Write the formula for the conjugate base for each of the following acids:
a. HCO3-

검증된 단계별 안내

Identify the definition of a conjugate base: A conjugate base is formed when an acid donates a proton (H⁺). This means you remove one H⁺ ion from the acid and adjust the charge accordingly.
Start with the given acid, HCO₃⁻. This is bicarbonate, which has a negative charge of -1.
Remove one H⁺ ion from HCO₃⁻. Removing H⁺ means subtracting one hydrogen atom and reducing the charge by 1 (since H⁺ has a +1 charge).
After removing H⁺, the remaining species is CO₃²⁻. This is carbonate, which now has a charge of -2.
Write the formula for the conjugate base: The conjugate base of HCO₃⁻ is CO₃²⁻.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Conjugate Base

A conjugate base is the species that remains after an acid donates a proton (H⁺). In the context of Brønsted-Lowry acid-base theory, when an acid loses a proton, it transforms into its conjugate base, which can then potentially accept a proton in future reactions.

Acid-Base Reaction

An acid-base reaction involves the transfer of protons between reactants. Acids are proton donors, while bases are proton acceptors. Understanding this dynamic is crucial for identifying conjugate pairs, as each acid has a corresponding conjugate base formed after the proton transfer.

Bicarbonate Ion (HCO₃⁻)

The bicarbonate ion (HCO₃⁻) is a weak acid that can donate a proton to form its conjugate base, carbonate (CO₃²⁻). Recognizing the structure and behavior of bicarbonate is essential for determining its conjugate base, as it illustrates the principles of acid-base chemistry in action.
