Verified step by step guidance
1
Identify the type of reaction occurring between lithium hydroxide (LiOH) and hydrobromic acid (HBr). This is an acid-base neutralization reaction where an acid reacts with a base to form a salt and water.
Write the balanced chemical equation for the reaction: $\mathrm{LiOH + HBr \rightarrow LiBr + H_2O}$.
Recognize that lithium hydroxide (LiOH) provides the lithium ion ($\mathrm{Li^+}$) and hydroxide ion ($\mathrm{OH^-}$), while hydrobromic acid (HBr) provides the hydrogen ion ($\mathrm{H^+}$) and bromide ion ($\mathrm{Br^-}$).
During the reaction, the hydrogen ion ($\mathrm{H^+}$) from HBr combines with the hydroxide ion ($\mathrm{OH^-}$) from LiOH to form water ($\mathrm{H_2O}$), and the lithium ion ($\mathrm{Li^+}$) combines with the bromide ion ($\mathrm{Br^-}$) to form the salt lithium bromide ($\mathrm{LiBr}$).
Conclude that the salt formed in this neutralization reaction is lithium bromide ($\mathrm{LiBr}$), which corresponds to the correct answer.
