Conjugate base is species form by the removal of proton from an acid
HCL--> H* + Cl-
acid. conjugate acid
To answer this question, we need to think about the Brønsted-Lowry definition of acids and bases.
* Brønsted-Lowry Acid: A substance that donates a proton (H⁺).
* Brønsted-Lowry Base: A substance that accepts a proton (H⁺).
Conjugate Acid-Base Pairs
When an acid donates a proton, what's left is called its conjugate base. Similarly, when a base accepts a proton, it becomes its conjugate acid.
Analyzing the Options
* A. can neutralize each other to form a salt: While acids and bases can neutralize each other, this statement doesn't specifically describe the relationship between an acid and its conjugate base.
* B. differ only by a proton: This is the correct answer! As we saw in the definition and the example, an acid and its conjugate base differ by the presence or absence of a proton (H⁺).
* C. differ only by the opposite charges they carry: While there's often a charge difference, it's not the only difference. The key difference is the proton.
* D. are always neutral substances: Acids can be neutral or charged (like H₃O⁺), and bases can also be neutral or charged (like Cl⁻). So, this isn't always true.
The Answer
The correct answer is B. differ only by a proton.
Great job thinking about acids and bases! It's a fundamental concept in chemistry. Do you have any more questions about this?
A is the answer because a conjugate base is just like a base which when reacted with acid neutralizes it to water and salt...(I STAND TO BE CORRECTED)
