Which of the following is both an Arrhenius base and Bronsted-Lowry base? a. BF3 b. NaOH c. HNO3 d. NH3<\/p>\n\n\n\n

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

The correct answer is b. NaOH<\/strong>.<\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

Arrhenius Base<\/strong>:
According to the Arrhenius definition, a base is a substance that dissociates in water to produce hydroxide ions (OH\u207b).<\/p>\n\n\n\n

    \n
  • NaOH<\/strong> dissociates in water as follows:
    NaOH\u00a0(aq)\u2192Na+(aq)+OH\u2212(aq)\\text{NaOH (aq)} \\rightarrow \\text{Na}^+(aq) + \\text{OH}^-(aq)NaOH\u00a0(aq)\u2192Na+(aq)+OH\u2212(aq)
    Since NaOH produces hydroxide ions in water, it is an Arrhenius base.<\/li>\n<\/ul>\n\n\n\n

    Bronsted-Lowry Base<\/strong>:
    According to the Bronsted-Lowry definition, a base is a substance that accepts a proton (H\u207a).<\/p>\n\n\n\n

      \n
    • NaOH<\/strong> in water acts as a Bronsted-Lowry base because the hydroxide ion (OH\u207b) can accept a proton (H\u207a) from an acid to form water:
      OH\u2212(aq)+H+(aq)\u2192H2O\\text{OH}^-(aq) + \\text{H}^+(aq) \\rightarrow \\text{H}_2\\text{O}OH\u2212(aq)+H+(aq)\u2192H2\u200bO
      Thus, NaOH is also a Bronsted-Lowry base because it accepts a proton.<\/li>\n<\/ul>\n\n\n\n

      Why other options are not correct:<\/h3>\n\n\n\n
        \n
      • a. BF3<\/strong>: BF\u2083 is a Lewis acid, but it does not fit either the Arrhenius or Bronsted-Lowry definition of a base. It does not release OH\u207b or accept H\u207a in solution.<\/li>\n\n\n\n
      • c. HNO3<\/strong>: HNO\u2083 is an acid, not a base. It donates protons (H\u207a) in solution, making it a Bronsted-Lowry acid and an Arrhenius acid.<\/li>\n\n\n\n
      • d. NH3<\/strong>: Ammonia (NH\u2083) is a Bronsted-Lowry base because it can accept a proton to form NH\u2084\u207a. However, it does not produce OH\u207b ions directly from dissociation in water, so it is not an Arrhenius base.<\/li>\n<\/ul>\n\n\n\n
