For the reaction CH3COOH- CH3COO + H+, which of the following statements is true?
CH3COO- is an Arrhenius base.
CH3COO- is a conjugate
CH3COOH- is a Brønsted-Lowry acid. <my choice
CH3COOH- is a Brønsted-Lowry base.
You omitted the arrow.
CH3COOH ==> CH3COO^- + H^+
CH3COOH is an acid because it is donating a proton. The CH3COO^- is its conjugate base.
Your choice is right but I want to point out that CH3COO^- is its conjugate base. Technically, answer B is correct, also, although the word "base" is not there; it IS a conjugate.
naturally a is correct
Well, it seems like you're looking for a little humor in your answer, so here it goes!
CH3COO- walks into a chemistry bar and starts talking to H+. CH3COOH- suddenly jumps in, saying "Hey, I think I'm a Brønsted-Lowry acid!" CH3COO- raises an eyebrow and says, "Well, looks like I'm just a simple conjugate."
So, the true statement here is that CH3COOH- is indeed a Brønsted-Lowry acid. But don't worry, CH3COO- still has plenty of other qualities to be proud of!
You are correct! CH3COOH- is a Brønsted-Lowry acid. In the given reaction, CH3COOH donates a proton (H+) to form CH3COO-. According to the Brønsted-Lowry acid-base theory, an acid is a substance that can donate a proton.
To determine which statement is true, we need to understand the concepts of Arrhenius bases and acids, as well as Brønsted-Lowry acids and bases.
According to Arrhenius theory, an acid is a substance that releases hydrogen ions (H+) when dissolved in water, while a base releases hydroxide ions (OH-). Based on this theory, we can see that in the given reaction CH3COOH (acetic acid) releases an H+ ion, indicating that it is indeed an acid. So, CH3COOH- is a Brønsted-Lowry acid.
In Brønsted-Lowry theory, an acid is defined as a substance that donates a proton (H+), while a base is a substance that accepts a proton. In the given reaction, CH3COOH donates a proton and forms CH3COO- (acetate ion). Therefore, CH3COO- is the conjugate base of the acid, CH3COOH.
Hence, the correct statement is: CH3COOH- is a Brønsted-Lowry acid.
