Answer the following questions about Fe and Al compounds. Use the following reactions that involve F — Equilibrium Chemistry Question
Problem Context
Answer the following questions about Fe and Al compounds.
Use the following reactions that involve Fe and Al compounds to answer parts (b) and (c).
In distilled water
Reaction 1: Fe2O3(s) + 3 H2O(l) → 2 Fe(OH)3(s)
Reaction 2: Al2O3(s) + 3 H2O(l) → 2 Al(OH)3(s)
In base
Reaction 3: Fe(OH)3(s) + NaOH(aq) → no reaction
Reaction 4: Al(OH)3(s) + NaOH(aq) → NaAl(OH)4(aq)
In acid
Reaction 5: Fe(OH)3(s) + 3 HCl(aq) → FeCl3(aq) + 3 H2O(l)
Reaction 6: Al(OH)3(s) + 3 HCl(aq) → AlCl3(aq) + 3 H2O(l)
Reaction 7: NaAl(OH)4(aq) + HCl(aq) → Al(OH)3(s) + NaCl(aq) + H2O(l)
When heated
Reaction 8: 2 Fe(OH)3(s) -heat→ Fe2O3(s) + 3 H2O(g)
Reaction 9: 2 Al(OH)3(s) -heat→ Al2O3(s) + 3 H2O(g)
