KCET 2023 | Coordination Compounds Question 9 | Chemistry

When $$\mathrm{FeCl}_3$$ is added to excess of hot water gives a sol '$$X$$'. When $$\mathrm{FeCl}_3$$ is added to $$\mathrm{NaOH}(a q)$$ solution, gives sol '$$Y$$'

$$X$$ and $$Y$$ formed in the above processes respectively are

$$\mathrm{Fe}_2 \mathrm{O}_3 \cdot x \mathrm{H}_2 \mathrm{O} / \mathrm{OH}^{-}$$ and $$\mathrm{Fe}_2 \mathrm{O}_3 \cdot x \mathrm{H}_2 \mathrm{O} / \mathrm{Fe}^{3+}$$

$$\mathrm{Fe}_2 \mathrm{O}_3 \cdot x \mathrm{H}_2 \mathrm{O} / \mathrm{H}^{+}$$ and $$\mathrm{Fe}_2 \mathrm{O}_3 \cdot x \mathrm{H}_2 \mathrm{O} / \mathrm{Na}^{+}$$

$$\mathrm{Fe}_2 \mathrm{O}_3 \cdot x \mathrm{H}_2 \mathrm{O} / \mathrm{Cl}^{-}$$ and $$\mathrm{Fe}_2 \mathrm{O}_3 \cdot x \mathrm{H}_2 \mathrm{O} / \mathrm{OH}^{-}$$

$$\mathrm{Fe}_2 \mathrm{O}_3 \cdot x \mathrm{H}_2 \mathrm{O} / \mathrm{Fe}^{3+}$$ and $$\mathrm{Fe}_2 \mathrm{O}_3 \cdot x \mathrm{H}_2 \mathrm{O} / \mathrm{OH}^{-}$$
