Question

hi(aq) + sr(oh)₂(aq) →
express your answer as a chemical equation. identify all of the phases in your answer.
a chemical reaction does not occur for this question.

Explanation:

Step1: Write the products of the acid - base reaction

Hydroiodic acid (\(HI\)) reacts with strontium hydroxide (\(Sr(OH)_2\)) in an acid - base (neutralization) reaction. The general form of an acid - base reaction is \(acid+base
ightarrow salt + water\).
For \(HI\) (a strong acid) and \(Sr(OH)_2\) (a strong base), the salt formed is \(SrI_2\) (strontium iodide) and water (\(H_2O\)).
The unbalanced equation is \(HI(aq)+Sr(OH)_2(aq)
ightarrow SrI_2(aq)+H_2O(l)\)

Step2: Balance the chemical equation

• Balance the iodine atoms: There are 2 iodine atoms in \(SrI_2\), so we need 2 moles of \(HI\).
• Balance the hydrogen and oxygen atoms: After putting a coefficient of 2 in front of \(HI\), we have \(2HI(aq)+Sr(OH)_2(aq)

ightarrow SrI_2(aq)+2H_2O(l)\)

Answer:

\(2HI(aq)+Sr(OH)_2(aq)
ightarrow SrI_2(aq)+2H_2O(l)\)
