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

The correct balanced chemical equation for the reaction between potassium hydroxide (KOH) and hydrobromic acid (HBr) in aqueous solution is:<\/p>\n\n\n\n

KOH (aq) + HBr (aq) \u2192 H2O (l) + KBr (aq)<\/strong><\/p>\n\n\n\n

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

This is a typical acid-base neutralization reaction, where an aqueous base (KOH) reacts with an aqueous acid (HBr) to form water and an ionic salt (KBr).<\/p>\n\n\n\n

    \n
  • KOH<\/strong> is potassium hydroxide, a strong base. In an aqueous solution, it dissociates into K\u207a<\/strong> (potassium ions) and OH\u207b<\/strong> (hydroxide ions).<\/li>\n\n\n\n
  • HBr<\/strong> is hydrobromic acid, a strong acid. In water, it dissociates into H\u207a<\/strong> (hydrogen ions) and Br\u207b<\/strong> (bromide ions).<\/li>\n<\/ul>\n\n\n\n

    In a neutralization reaction, the H\u207a<\/strong> ions from the acid combine with the OH\u207b<\/strong> ions from the base to form H2O<\/strong> (water). The remaining ions, K\u207a<\/strong> and Br\u207b<\/strong>, combine to form KBr<\/strong>, which is potassium bromide, a soluble ionic salt in water.<\/p>\n\n\n\n

    Physical States:<\/h3>\n\n\n\n
      \n
    • KOH (aq)<\/strong> indicates that potassium hydroxide is dissolved in water, forming an aqueous solution.<\/li>\n\n\n\n
    • HBr (aq)<\/strong> indicates that hydrobromic acid is dissolved in water, also forming an aqueous solution.<\/li>\n\n\n\n
    • H2O (l)<\/strong> represents liquid water, the product formed from the neutralization.<\/li>\n\n\n\n
    • KBr (aq)<\/strong> indicates that potassium bromide is dissolved in water, forming an aqueous solution.<\/li>\n<\/ul>\n\n\n\n

      This reaction is exothermic, releasing heat as the ions form water.<\/p>\n\n\n\n
