NaOH is a Bronsted-Lowry base because?
1) it is a polar molecule
2) it can dissolve in water
3) it is a hydroxide donor
4) it is a proton acceptor<\/p>\n\n\n\n
The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n The correct answer is: 4) it is a proton acceptor.<\/strong><\/p>\n\n\n\n The Bronsted-Lowry theory defines acids as proton (H\u207a) donors and bases as proton acceptors. This concept revolves around the transfer of protons (hydrogen ions) in a chemical reaction.<\/p>\n\n\n\n In summary, NaOH qualifies as a Bronsted-Lowry base because the OH\u207b ions it generates in solution readily accept protons from acids, exemplifying the fundamental definition of a base in this theory.<\/p>\n","protected":false},"excerpt":{"rendered":" NaOH is a Bronsted-Lowry base because?1) it is a polar molecule2) it can dissolve in water3) it is a hydroxide donor4) it is a proton acceptor The Correct Answer and Explanation is: The correct answer is: 4) it is a proton acceptor.

Why NaOH is a Bronsted-Lowry Base:<\/h4>\n\n\n\n
\n
Sodium hydroxide (NaOH) is an ionic compound that dissociates completely in water into sodium ions (Na\u207a) and hydroxide ions (OH\u207b). The dissociation reaction is:
[
\\text{NaOH} \\rightarrow \\text{Na\u207a} + \\text{OH\u207b}
]<\/li>\n\n\n\n
The hydroxide ion (OH\u207b) produced during dissociation is highly reactive and has a strong affinity for protons (H\u207a). When OH\u207b encounters an H\u207a ion in solution, it readily combines to form water (H\u2082O). This reaction can be written as:
[
\\text{OH\u207b} + \\text{H\u207a} \\rightarrow \\text{H\u2082O}
]
Here, OH\u207b acts as a Bronsted-Lowry base because it accepts a proton from an acid.<\/li>\n<\/ol>\n\n\n\nWhy the Other Options Are Incorrect:<\/h4>\n\n\n\n
\n
While polarity plays a role in solubility and interactions, being polar does not directly classify a substance as a Bronsted-Lowry base. NaOH is ionic, not molecular.<\/li>\n\n\n\n
The ability to dissolve in water is a physical property and is not directly related to its behavior as a Bronsted-Lowry base.<\/li>\n\n\n\n
Although NaOH produces hydroxide ions, this is part of its dissociation process, not its classification under the Bronsted-Lowry theory. The key is the ability to accept a proton, not just produce OH\u207b.<\/li>\n<\/ol>\n\n\n\n
