Write out chemical equations to explain why: 1. aqueous sodium carbonate is basic, 2. aqueous aluminum chloride is acidic, and 3. aqueous potassium iodide is neutral.
1. Na₂CO₃(aq) + 2 H₂O(l)→2 NaOH(aq) + CO₂(aq) + H₂O(l)
2. AlCl₃(aq) + 3 H₂O(l)→Al(OH)₃(aq) + 3 HCl(aq)
3. KI(aq) + H₂O(l)→KOH(aq) + HI(aq)
