In the reaction of aqueous aluminum chloride with aqueous potassium hydroxide, the products formed are aluminum hydroxide and potassium chloride. What is the correct balanced equation for this reaction?
1)
AlCl3(aq) + KOH(aq) Al(OH) (aq) + KCl3(s)
2)
Al3Cl (aq) + 3KOH(aq) 3Al(OH) (s) + 3KCl(aq)
3)
AlCl3(aq) + 3KOH(aq) Al (OH)3(s) + 3KCl(aq)
4)
AlCl3(aq) + K(OH)3(aq) Al(OH)3(aq) + KCl3(s)
