Question 1 2 / 2 pts (CO 3) Which of the statements listed below is true according to Bronsted-Lowry definitions? An acid is a proton acceptor. A base produces H+ ions in aqueous solutions. A base is a proton donor. Correct! A base is a proton acceptor. An acid acts as the solvent. See Chapter 7. The Brønsted-Lowry theory describes acid-base interactions in terms of proton transfer between chemical species. According to this theory, an acid is any species that can donate a proton (H+), and a base is any species that can accept a proton. So, an "acid" must contain a hydrogen that can dissociate as H+, and a base must have at least one lone pair of electrons to form a new bond with a proton. Question 2 2 / 2 pts (CO 3) Ammonia (NH3) accepts a proton from water. Which of the statements listed below is true according to Bronsted-Lowry definitions? Correct! Ammonia is a base. Ammonia is an acid. Ammonia produces H+ ions in aqueous solutions.
