Chromium(III) nitrate solution contains Cr³⁺ and NO₃⁻ ions.
Potassium hydroxide solution contains K⁺ and OH⁻ ions.
Cr(OH)₃ is insoluble in water, while KNO₃ is soluble.
Thus, the reaction is the precipitation of Cr(OH)₃. The net ionic equation is thus :
Cr³⁺(aq) + 3OH⁻(aq) → Cr(OH)₃(s)
Potassium hydroxide solution contains K⁺ and OH⁻ ions.
Cr(OH)₃ is insoluble in water, while KNO₃ is soluble.
Thus, the reaction is the precipitation of Cr(OH)₃. The net ionic equation is thus :
Cr³⁺(aq) + 3OH⁻(aq) → Cr(OH)₃(s)
