Write a balanced chemical equation for the aqueous reaction between potassium hydroxide and hydrobromic acid. Include physical states.

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)<\/p>\n\n\n\n

Explanation:
Reaction Type: This is an acid-base neutralization reaction. Potassium hydroxide (KOH), a strong base, reacts with hydrobromic acid (HBr), a strong acid, to form water (H2O) and potassium bromide (KBr), which is an ionic salt.<\/p>\n\n\n\n

Physical States:<\/p>\n\n\n\n

KOH (aq): Potassium hydroxide is commonly dissolved in water, so it’s in aqueous form (aq).<\/p>\n\n\n\n

HBr (aq): Hydrobromic acid is also an aqueous solution when it is dissolved in water.<\/p>\n\n\n\n

H2O (l): Water is the product of the neutralization reaction and is in the liquid state.<\/p>\n\n\n\n

KBr (aq): Potassium bromide is an ionic compound that dissociates into K+ and Br- ions in water, making it aqueous (aq).<\/p>\n\n\n\n

Why KOH (aq) and HBr (aq)?<\/p>\n\n\n\n

For the reaction to occur in aqueous form, both KOH and HBr must be in solution (aq). If either of these compounds is in a solid or gaseous state, the reaction would not take place as efficiently or in the same manner.<\/p>\n\n\n\n

KOH (s) and HBr (g) are not typical forms for a neutralization reaction because potassium hydroxide is usually dissolved in water for easy dissociation, and hydrobromic acid is most often encountered as an aqueous solution rather than a gas.<\/p>\n\n\n\n

Balanced Equation:<\/p>\n\n\n\n

There is no need for coefficients to balance the equation in this case, as the number of atoms on both sides of the equation is already equal.<\/p>\n\n\n\n

The products of the reaction are water (H2O) and potassium bromide (KBr), and both are formed in the correct proportions from the reactants.<\/p>\n\n\n\n

Thus, the balanced equation is:<\/p>\n\n\n\n

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