All Brønsted-Lowry acids
A. are aqueous solutions.
B. can act as Arrhenius acids.
C. donate protons.
D. all of the above
I think it is D, but I also think it is c can you please tell me if either of these answers are right thanks
I think B is true. C is true. But A is not true; for example, NH3 is analogous to H2O in liquid NH3. Just as
H2O + H2O ==> H3O^+ + OH^- in aqueous solution, then
NH3 + NH3 ==> NH4^+ + NH2^- in liquid NH3. So I don't know about the answer. If it were D that is true only if A is true. The way your question is worded leads me to believe that only one answer is true so it can't be B AND C. Makes me think the answer is A and the person making up the question doesn't know A is not true.
The correct answer is D. All Brønsted-Lowry acids can act as Arrhenius acids and can also donate protons. Let's break it down:
A. Aqueous solutions: Brønsted-Lowry acids can exist in both aqueous (water) and non-aqueous solutions. Therefore, not all Brønsted-Lowry acids are aqueous solutions.
B. Arrhenius acids: Arrhenius acids are substances that increase the concentration of hydrogen ions (H+) when dissolved in water. Brønsted-Lowry acids can act as Arrhenius acids because they can donate protons (H+) to water, leading to an increase in H+ concentration. So, if a substance is a Brønsted-Lowry acid, it can also be an Arrhenius acid.
C. Donate protons: In the Brønsted-Lowry theory, an acid is a substance that donates a proton (H+), while a base is a substance that accepts a proton. Therefore, all Brønsted-Lowry acids donate protons.
Since all the statements are true, the correct answer is D, "all of the above."
