All Brønsted-Lowry acids
A. are aqueous solutions.
B. can act as Arrhenius acids.
C. donate protons.
D. all of the above
I am a little confused. I think it is D, but I'm second guessing myself with C
See my response above. Both B and C are correct.
To determine the correct answer, let's break down the definitions of Brønsted-Lowry acids and Arrhenius acids:
1. Brønsted-Lowry acids: According to the Brønsted-Lowry definition, an acid is a substance that can donate a proton (H+ ion).
2. Arrhenius acids: According to the Arrhenius definition, an acid is a substance that, when dissolved in water, increases the concentration of H+ ions.
Now, let's analyze each answer choice:
A. Are all Brønsted-Lowry acids aqueous solutions?
This statement is not accurate. Brønsted-Lowry acids can be aqueous solutions, but they can also exist in other forms, such as gaseous or solid acids. Therefore, this option is not correct.
B. Can all Brønsted-Lowry acids act as Arrhenius acids?
This statement is also not accurate. While some Brønsted-Lowry acids can act as Arrhenius acids when dissolved in water, not all Brønsted-Lowry acids are necessarily aqueous solutions. Hence, this option is not correct.
C. Do all Brønsted-Lowry acids donate protons?
This statement is true. One of the defining characteristics of a Brønsted-Lowry acid is the ability to donate a proton (H+ ion). Therefore, this option is correct.
D. Do all of the above apply to Brønsted-Lowry acids?
This answer choice encompasses all the previous options, stating that Brønsted-Lowry acids are aqueous solutions, can act as Arrhenius acids, and donate protons. Given that options A and B are incorrect, option D is the correct choice.
Therefore, the correct answer is D) all of the above, as it correctly includes the statement that Brønsted-Lowry acids donate protons (C) while also accounting for the incorrect statements in options A and B.
