The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

The correct answer is:
C it is a proton acceptor.<\/strong><\/p>\n\n\n\n

Explanation:<\/strong><\/p>\n\n\n\n

According to the Br\u00f8nsted-Lowry theory, an acid is defined as a substance that donates a proton (H\u207a ion), while a base is a substance that accepts a proton. This definition is broader than the Arrhenius definition, which only considers acids and bases in aqueous solutions and requires acids to produce H\u207a ions and bases to produce OH\u207b ions.<\/p>\n\n\n\n

Barium hydroxide, Ba(OH)2\\mathrm{Ba(OH)_2}Ba(OH)2\u200b, is a strong base that dissociates completely in water to produce barium ions Ba2+\\mathrm{Ba^{2+}}Ba2+ and hydroxide ions OH\u2212\\mathrm{OH^-}OH\u2212. While it is true that it contains hydroxide ions, its classification as a Br\u00f8nsted-Lowry base is not based on the fact that it contains or donates OH\u207b, but rather on the fact that the OH\u207b ions it releases can accept protons<\/strong>.<\/p>\n\n\n\n

In a Br\u00f8nsted-Lowry reaction, the hydroxide ion OH\u2212\\mathrm{OH^-}OH\u2212, which results from the dissociation of barium hydroxide, acts as the base because it accepts a proton<\/strong> from an acid to form water:OH\u2212+H+\u2192H2O\\mathrm{OH^- + H^+ \\rightarrow H_2O}OH\u2212+H+\u2192H2\u200bO<\/p>\n\n\n\n

This reaction demonstrates the proton-accepting nature of the base. Therefore, barium hydroxide is considered a Br\u00f8nsted-Lowry base because the OH\u2212\\mathrm{OH^-}OH\u2212 ions it provides accept protons during acid-base reactions.<\/p>\n\n\n\n

Option A is misleading because \u201chydroxide donor\u201d is not a recognized concept in Br\u00f8nsted-Lowry theory. Option B repeats A\u2019s error. Option D is incorrect because the ability to dissolve in water is a physical property and does not define acid-base behavior in the Br\u00f8nsted-Lowry context.<\/p>\n\n\n\n

Hence, the correct explanation is that barium hydroxide acts as a Br\u00f8nsted-Lowry base because it is a proton acceptor<\/strong> through the OH\u2212\\mathrm{OH^-}OH\u2212 ions it produces.<\/p>\n\n\n\n
