What are the products formed when HI(aq) reacts with LiOH(aq)?
A
LiH(aq) + IOH(aq)
B
H2I(aq) + LiO(l)
C
LiI(aq) + H2O(l)
D
LiOH(aq) + HI(aq)
Verified step by step guidance1
Identify the reactants in the chemical equation: HI(aq) and LiOH(aq).
Recognize that this is a neutralization reaction between an acid (HI) and a base (LiOH).
In a neutralization reaction, the acid (HI) donates a proton (H⁺) to the hydroxide ion (OH⁻) from the base (LiOH), forming water (H₂O).
The remaining ions, Li⁺ from LiOH and I⁻ from HI, combine to form the salt lithium iodide (LiI).
Write the balanced chemical equation for the reaction: HI(aq) + LiOH(aq) → LiI(aq) + H₂O(l).
