Question

write the balanced net ionic equation for the reaction when aluminum nitrate and potassium iodide are mixed in aqueous solution. if no reaction occurs, simply write only nr. be sure to include the proper phases for all species within the reaction.

Explanation:

Step1: Write the formulae

Aluminium nitrate is \(Al(NO_3)_3\), potassium iodide is \(KI\). In aqueous solution, \(Al(NO_3)_3\) dissociates as \(Al^{3 + }(aq)+3NO_3^-(aq)\) and \(KI\) dissociates as \(K^{+}(aq)+I^-(aq)\).

Step2: Check for reaction

According to solubility rules, aluminium iodide \(AlI_3\) is soluble in water and potassium nitrate \(KNO_3\) is also soluble in water. So, no precipitation, no gas - evolution, no acid - base reaction (since there is no \(H^+\) or \(OH^-\) involved in a non - redox sense here and no change in oxidation states of elements (\(Al: + 3\), \(N: + 5\), \(O:-2\), \(K: + 1\), \(I:-1\))).

Answer:

NR
