Question

Which of the following equations is the net ionic equation for the precipitation of chromium(III) hydroxide from an aqueous mixture of potassium hydroxide and chromium(III) nitrate?

Accepted Answer

$$Cr^{3+}(aq) + 3$$ $$OH^{–}(aq$$) → Cr(OH)_{3}(s)

Answer

$$Cr^{+}(aq) + 3$$ $$OH^{3–}(aq$$) → $$Cr_{3}OH(s)$$

Answer

$$Cr^{3+}(aq$$) + $$OH^{–}(aq$$) → $$CrOH^{2+}(s)$$

Answer

$$Cr^{3+}(aq$$) + $$OH^{3–}(aq$$) → CrOH(s)
